 append_save M-file function

 Objective: be able to add variables to existing save files. Works for
 all the types of save files that "save" supports.
 
 Input: 
 1) A string which specifies the existing save file.
 2) The options you need to pass to the 'save' function to save to the
 file type that you want.
 3) A 1x2 cell, with the first element being a string representation
 of the variable/symbol that you're trying to add, followed by the
 actual variable/symbol itself.
 4) Any number of additional 1x2 cells, following the same format as
 the 3rd argument specified immediately before this one.

 Output:
 Currently, none. But there might be some debugging / error-code
 messages in the future.

 Example:
 octave> B = ones(2,2);
 octave> append_save( "test.txt", "-binary", {"B", B } )

 Check Octave / Matlab environment for spreadsheet I/O support.

   usage:  [ RETVAL ] = chk_spreadsheet_support ( [/PATH/TO/JARS], [,DEBUG_LEVEL] [,PATH_TO_OOO])

 CHK_SPREADSHEET_SUPPORT first checks ActiveX (native MS-Excel); then
 Java JRE presence, then Java support (builtin/activated (Matlab) or
 added tru octave-forge Java package (Octave); then check existing
 javaclasspath for Java class libraries (.jar) needed for various
 Java-based spreadsheet I/O interfaces.
 If desired the relevant classes can be added to the dynamic
 javaclasspath. In that case the path name to the directory 
 containing these classes should be specified as input argument
 with -TAKE NOTICE- /forward/ slashes. In these jars reside in
 different directories, multiple calls to chk_spreadsheet_support
 can be made.

     Input arguments (all are optional, but the order is important):
 /PATH/TO/JARS = (string) path (relative or absolute) to a
                 subdirectory where java class libraries (.jar)
                 for spreadsheet I/O reside. Can be [] or ''
 DEBUG_LEVEL   = (integer) between [0 (no output) .. 3 (full output]
 PATH_TO_OOO   = (string) installation directory of Openffice.org,
                 usually (but not guaranteed):
                 - Windows: C:\Program Files\OpenOffice.org
                 - *nix:    /usr/lib/ooo
                 - Mac OSX: ?????
                 IMPORTANT: PATH_TO_OOO should be such that both:
                 1. PATH_TO_OOO/program/       
                  and
                 2. PATH_TO_OOO/ure/.../ridl.jar
                 resolve OK
     Returns:
 RETVAL        =  0 No spreadsheet I/O support found
               <> 0 At least one spreadsheet I/O interface found. RETVAL
                  RETVAL will be set to the sum of values for found interfaces:
                  ---------- XLS (Excel) interfaces: ----------
                    1 = COM (ActiveX / Excel)
                    2 = POI (Java / Apache POI)

 -- Function File: ex = fexist (file, tspec, aspec)
     Checks whether a file exists.  FILE is the queried file path.
     TSPEC is a combination of letters f,d,p,S, corresponding to file
     types:
        * f: regular file

        * d: directory

        * p: named pipe (FIFO special file)

        * S: socket

     The query is true if the actual file type matches any of the
     specified options.

     ASPEC is a combination of letters r,w,x, corresponding to queried
     access privileges to the file. The query is true if the current
     user has all the spefied types of access, either through "user",
     "group" or "other" specs.

 -- Function File: [ TOPROW#, BOTTOMROW#, LEFTCOL#, RIGHTCOL# ] =
          getusedrange (SPPTR, SHINDEX#)
     Find occupied data range in worksheet SHINDEX# in a spreadsheet
     pointed to in struct SPPTR (either MS-Excel or OpenOffice_org
     Calc).

     SHINDEX# must be numeric and is 1-based. SPPTR can either refer to
     an MS-Excel spreadsheet (spptr returned by xlsopen) or an
     OpenOffice.org Calc spreadsheet (spptr returned by odsopen).  None
     of these inputs are checked!

     Be aware that especially for OpenOffice.org Calc (ODS) spreadsheets
     the results can only be obtained by counting all cells in all rows;
     this can be fairly time-consuming. Reliable ods data size results
     can only be obtained using UNO interface.  For the ActiveX (COM)
     interface the underlying Visual Basic call relies on cached range
     values and counts empty cells with only formatting too, so COM
     returns only approximate (but then usually too big) range values.

     Examples:

            [trow, brow, lcol, rcol] = getusedrange (ods2, 3);
            (which returns the outermost row & column numbers of the rectangle
             enveloping the occupied cells in the third sheet of an OpenOffice_org
             Calc spreadsheet pointedto in struct ods2)

            [trow, brow, lcol, rcol] = getusedrange (xls3, 3);
            (which returns the outermost row & column numbers of the rectangle
             enveloping the occupied cells in the third sheet of an Excel
             spreadsheet pointed to in struct xls3)

# length: 1521
 Returns a valid json string that will describe object; the string will
 be in a compact form (no spaces or line breaks).

 It will map simple octave values this way:
   function handles: string with the name of the function
   double (numbers): depends:
     If it's real it will map to a string representing that number
     If it's complex it will map to an object with the next properties:
       real: real part of the number
       imag: imaginary part of the number
   char: A string enclosed by double quotes representing that character
 And will map more complex octave values this other way:
   struct: an object with properties equal to the struct's field names
     and value equal to the json counterpart of that field
   cell: it will be mapped depending on the value of the cell (for
     example {i} will be mapped to an object with real=0 and imag=1)
   vectors or cell arrays: it will map them to a corresponding js
     array (same size) with the values transformed to their json
     counterpart (Note: that in javascript all arrays are like octave's
     cells ,i.e. they can store different type and size variables)
   strings or char vectors: they will be mapped to the same string
     enclosed by double quotes
 Other octave values will be mapped to a string enclosed by double
 quotes with the value that the class() function returns
 It can handle escape sequences and special chars automatically.
 If they're valid in JSON it will keep them if not they'll be
 escaped so they can become valid

 -- Function File: [ ODS, RSTATUS ] = oct2ods (ARR, ODS, WSH, RANGE)
 -- Function File: [ ODS, RSTATUS ] = oct2ods (ARR, ODS, WSH, RANGE,
          OPTIONS)
     Transfer data to an OpenOffice_org Calc spreadsheet previously
     opened by odsopen().

     Data in 1D/2D array ARR are transferred into a cell range RANGE in
     sheet WSH. ODS must have been made earlier by odsopen(). Return
     argument ODS should be the same as supplied argument ODS and is
     updated by oct2ods. A subsequent call to odsclose is needed to
     write the updated spreadsheet to disk (and -if needed- close the
     Java invocation holding the file pointer).

     ARR can be any 1D or 2D array containing numerical or character
     data (cellstr) except complex. Mixed numeric/text arrays can only
     be cell arrays.

     ODS must be a valid pointer struct created earlier by odsopen.

     WSH can be a number (sheet name) or string (sheet number).  In
     case of a yet non-existing Calc file, the first sheet will be used
     & named according to WSH.  In case of existing files, some checks
     are made for existing sheet names or numbers.  When new sheets are
     to be added to the Calc file, they are inserted to the right of
     all existing sheets. The pointer to the "active" sheet (shown when
     Calc opens the file) remains untouched.

     If RANGE omitted, the top left cell where the data will be put is
     supposed to be 'A1'; only a top left cell address can be specified
     as well. In these cases the actual range to be used is determined
     by the size of ARR.  Be aware that large data array sizes may
     exhaust the java shared memory space. For larger arrays,
     appropriate memory settings are needed in the file java.opts; then
     the maximum array size for the java-based spreadsheet options can
     be in the order of perhaps 10^6 elements.

     Optional argument OPTIONS, a structure, can be used to specify
     various write modes.  Currently the only option field is
     "formulas_as_text", which -if set to 1 or TRUE- specifies that
     formula strings (i.e., text strings starting with "=" and ending
     in a ")" ) should be entered as litteral text strings rather than
     as spreadsheet formulas (the latter is the default). As
     jOpenDocument doesn't support formula I/O at all yet, this option
     is ignored for the JOD interface.

     Data are added to the sheet, ignoring other data already present;
     existing data in the range to be used will be overwritten.

     If RANGE contains merged cells, also the elements of ARR not
     corresponding to the top or left Calc cells of those merged cells
     will be written, however they won't be shown until in Calc the
     merge is undone.

     Examples:

            [ods, status] = ods2oct (arr, ods, 'Newsheet1', 'AA31:GH165');
            Write array arr into sheet Newsheet1 with upperleft cell at AA31

            [ods, status] = ods2oct ({'String'}, ods, 'Oldsheet3', 'B15:B15');
            Put a character string into cell B15 in sheet Oldsheet3

 -- Function File: [ XLS, RSTATUS ] = oct2xls (ARR, XLS, WSH, RANGE,
          OPTIONS)
     Add data in 1D/2D CELL array ARR into a cell range specified in
     RANGE in worksheet WSH in an Excel spreadsheet file pointed to in
     structure XLS.  Return argument XLS equals supplied argument XLS
     and is updated by oct2xls.

     A subsequent call to xlsclose is needed to write the updated
     spreadsheet to disk (and -if needed- close the Excel or Java
     invocation).

     ARR can be any 1D or 2D array containing numerical or character
     data (cellstr) except complex. Mixed numeric/text arrays can only
     be cell arrays.

     XLS must be a valid pointer struct created earlier by xlsopen.

     WSH can be a number or string (max. 31 chars).  In case of a yet
     non-existing Excel file, the first worksheet will be used & named
     according to WSH - extra empty worksheets that Excel creates by
     default are deleted.  In case of existing files, some checks are
     made for existing worksheet names or numbers, or whether WSH
     refers to an existing sheet with a type other than worksheet
     (e.g., chart).  When new worksheets are to be added to the Excel
     file, they are inserted to the right of all existing worksheets.
     The pointer to the "active" sheet (shown when Excel opens the
     file) remains untouched.

     If RANGE is omitted or just the top left cell of the range is
     specified, the actual range to be used is determined by the size of
     ARR. If nothing is specified for RANGE the top left cell is
     assumed to be 'A1'.

     Data are added to the worksheet, ignoring other data already
     present; existing data in the range to be used will be overwritten.

     If RANGE contains merged cells, only the elements of ARR
     corresponding to the top or left Excel cells of those merged cells
     will be written, other array cells corresponding to that cell will
     be ignored.

     Optional argument OPTIONS, a structure, can be used to specify
     various write modes.  Currently the only option field is
     "formulas_as_text", which -if set to 1 or TRUE- specifies that
     formula strings (i.e., text strings starting with "=" and ending
     in a ")" ) should be entered as litteral text strings rather than
     as spreadsheet formulas (the latter is the default).

     Beware that -if invoked- Excel invocations may be left running
     silently in case of COM errors. Invoke xlsclose with proper
     pointer struct to close them.  When using Java, note that large
     data array sizes elements may exhaust the Java shared memory space
     for the default java memory settings.  For larger arrays,
     appropriate memory settings are needed in the file java.opts; then
     the maximum array size for the Java-based spreadsheet options may
     be in the order of 10^6 elements. In caso of UNO this limit is not
     applicable and spreadsheets may be much larger.

     Examples:

            [xlso, status] = xls2oct ('arr', xlsi, 'Third_sheet', 'AA31:AB278');

 -- Function File: [ RAWARR, ODS, RSTATUS ] = ods2oct (ODS, WSH, RANGE,
          OPTIONS)
     Read data contained within cell range RANGE from worksheet WSH in
     an OpenOffice_org Calc spreadsheet file pointed to in struct ODS.

     ODS is supposed to have been created earlier by odsopen in the
     same octave session.

     WSH is either numerical or text, in the latter case it is
     case-sensitive.  Note that in case of a numerical WSH this number
     refers to the position in the worksheet stack, counted from the
     left in a Calc window. The default is numerical 1, i.e. the
     leftmost worksheet in the ODS file.

     RANGE is expected to be a regular spreadsheet range format, or ""
     (empty string, indicating all data in a worksheet).  If no range
     is specified the occupied cell range will have to be determined
     behind the scenes first; this can take some time.

     Optional argument OPTIONS, a structure, can be used to specify
     various read modes by setting option fields in the struct to true
     (1) or false (0). Currently recognized option fields are:

    "formulas_as_text"
          If set to TRUE or 1, spreadsheet formulas (if at all present)
          are read as formula strings rather than the evaluated formula
          result values. This only works for the OTK and UNO interfaces.
          The default value is 0 (FALSE).

    'strip_array'
          Set the value of this field set to TRUE or 1 to strip the
          returned output array RAWARR from empty outer columns and
          rows. The spreadsheet cell rectangle limits from where the
          data actually came will be updated. The default value is
          FALSE or 0 (no cropping).

     If only the first argument ODS is specified, ods2oct will try to
     read all contents from the first = leftmost (or the only)
     worksheet (as if a range of '' (empty string) was specified).

     If only two arguments are specified, ods2oct assumes the second
     argument to be WSH. In that case ods2oct will try to read all data
     contained in that worksheet.

     Return argument RAWARR contains the raw spreadsheet cell data.
     Use parsecell() to separate numeric and text values from RAWARR.

     Optional return argument ODS contains the pointer struct. Field
     ODS.limits contains the outermost column and row numbers of the
     actually read cell range.

     Optional return argument RSTATUS will be set to 1 if the requested
     data have been read successfully, 0 otherwise.

     Erroneous data and empty cells turn up empty in RAWARR.  Date/time
     values in OpenOffice.org are returned as numerical values with
     base 1-1-0000 (same as octave). But beware that Excel spreadsheets
     rewritten by OpenOffice.org into .ods format may have numerical
     date cells with base 01-01-1900 (same as MS-Excel).

     When reading from merged cells, all array elements NOT
     corresponding to the leftmost or upper OpenOffice.org cell will be
     treated as if the "corresponding" cells are empty.

     Examples:

            A = ods2oct (ods1, '2nd_sheet', 'C3:ABS40000');
            (which returns the numeric contents in range C3:ABS40000 in worksheet
            '2nd_sheet' from a spreadsheet file pointed to in pointer struct ods1,
            into numeric array A)

            [An, ods2, status] = ods2oct (ods2, 'Third_sheet');

 -- Function File: [ ODS] = odsclose (ODS)
 -- Function File: [ ODS] = odsclose (ODS, FILENAME)
 -- Function File: [ ODS] = odsclose (ODS, "FORCE")
     Close the OpenOffice_org Calc spreadsheet pointed to in struct
     ODS, if needed write the file to disk.  odsclose will determine if
     the file must be written to disk based on information contained in
     ODS.  An empty pointer struct will be returned if no errors
     occurred.  Optional argument FILENAME can be used to write changed
     spreadsheet files to an other file than opened by odsopen().
     Optional string argument "FORCE" can be specified to force
     resetting the file pointer struct. However, in case of UNO, a
     hidden OOo invocation may linger on in memory then, preventing
     proper closing of Octave.

     You need the Java package >= 1.2.6 plus odfdom.jar + xercesImpl.jar
     and/or jopendocument-<version>.jar installed on your computer +
     proper javaclasspath set, to make this function work at all.  For
     UNO support, Octave-Java package >= 1.2.8 + latest fixes is
     imperative; furthermore the relevant classes had best be added to
     the javaclasspath by utility function chk_spreadsheet_support().

     ODS must be a valid pointer struct made by odsopen() in the same
     octave session.

     Examples:

            ods1 = odsclose (ods1);
            (Close spreadsheet file pointed to in pointer struct ods1; ods1 is reset)

     Query an OpenOffice_org spreadsheet file FILENAME (with ods
     suffix) for some info about its contents.

     If FILENAME is a recognizable OpenOffice.org spreadsheet file,
     FILETYPE returns the string "OpenOffice.org Calc spreadsheet", or
     '' (empty string) otherwise.

     If FILENAME is a recognizable OpenOffice.org Calc spreadsheet
     file, optional argument SH_NAMES contains a list (cell array) of
     sheet names contained in FILENAME, in the order (from left to
     right) in which they occur in the sheet stack.

     If you omit return arguments FILETYPE and SH_NAMES altogether,
     odsfinfo returns the sheet names and for each sheet the actual
     occupied data ranges to the screen.The occupied cell range will
     have to be determined behind the scenes first; this can take some
     time.

     odsfinfo execution can take its time for large spreadsheets as the
     entire spreadsheet has to be parsed to get the sheet names, let
     alone exploring used data ranges.

     By specifying a value of 'jod', 'otk' or 'uno' for REQINTF the
     automatic selection of the java interface is bypassed and the
     specified interface will be used (if at all present).

     Examples:

            exist = odsfinfo ('test4.ods');
            (Just checks if file test4.ods is a readable Calc file)

            [exist, names] = odsfinfo ('test4.ods');
            (Checks if file test4.ods is a readable Calc file and return a
             list of sheet names)

 -- Function File: ODS = odsopen (FILENAME)
 -- Function File: ODS = odsopen (FILENAME, READWRITE)
 -- Function File: ODS = odsopen (FILENAME, READWRITE, REQINTF)
     Get a pointer to an OpenOffice_org spreadsheet in the form of
     return argument ODS.

     Calling odsopen without specifying a return argument is fairly
     useless!

     To make this function work at all, you need the Java package >=
     1.2.5 plus ODFtoolkit (version 0.7.5 or 0.8.6+) & xercesImpl,
     and/or jOpenDocument, and/or OpenOffice.org (or clones) installed
     on your computer + proper javaclasspath set. These interfaces are
     referred to as OTK, JOD, and UNO resp., and are preferred in that
     order by default (depending on their presence).  For (currently
     experimental) UNO support, Octave-Java package 1.2.8 + latest
     fixes is imperative; furthermore the relevant classes had best be
     added to the javaclasspath by utility function
     chk_spreadsheet_support().

     FILENAME must be a valid .ods OpenOffice.org file name including
     .ods suffix. If FILENAME does not contain any directory path, the
     file is saved in the current directory.  For UNO bridge, filenames
     need to be in the form "file:///<path_to_file>/filename"; a URL
     will also work. If a plain file name is given (absolute or
     relative), odsopen() will transform it into proper form.

     READWRITE must be set to true or numerical 1 if writing to
     spreadsheet is desired immediately after calling odsopen(). It
     merely serves proper handling of file errors (e.g., "file not
     found" or "new file created").

     Optional input argument REQINTF can be used to override the ODS
     interface automatically selected by odsopen. Currently implemented
     interfaces are 'OTK' (Java/ODF Toolkit), 'JOD'
     (Java/jOpenDocument) and 'UNO' (Java/OpenOffice.org UNO bridge).

     Examples:

            ods = odsopen ('test1.ods');
            (get a pointer for reading from spreadsheet test1.ods)

            ods = odsopen ('test2.ods', [], 'JOD');
            (as above, indicate test2.ods will be read from; in this case using
             the jOpenDocument interface is requested)

 -- Function File: [ NUMARR, TXTARR, RAWARR, LIMITS] = odsread
          (FILENAME, WSH, RANGE, REQINTF)
     Read data contained from cell range RANGE in worksheet WSH in
     OpenOffice_org Calc spreadsheet file FILENAME.

     You need the octave-forge java package (> 1.2.6) and one or both of
     jopendocument-<version>.jar or preferrably: (odfdom.jar (versions
     0.7.5 or 0.8.6+) & xercesImpl.jar v. 2.9.1) in your javaclasspath.
     There is also experimental support invoking OpenOffice.org or
     clones through Java/UNO bridge.

     Return argument NUMARR contains the numeric data, optional return
     arguments TXTARR and RAWARR contain text strings and the raw
     spreadsheet cell data, respectively, and LIMITS is a struct
     containing the data origins of the various returned arrays.

     If FILENAME does not contain any directory, the file is assumed to
     be in the current directory. FILENAME should include the filename
     extension (.ods).

     WSH is either numerical or text, in the latter case it is
     case-sensitive and it should conform to OpenOffice.org Calc sheet
     name requirements.  Note that in case of a numerical WSH this
     number refers to the position in the worksheet stack, counted from
     the left in a Calc window. The default is numerical 1, i.e. the
     leftmost worksheet in the Calc file.

     RANGE is expected to be a regular spreadsheet range format, or ""
     (empty string, indicating all data in a worksheet).  If no range
     is specified the occupied cell range will have to be determined
     behind the scenes first; this can take some time.

     If only the first argument is specified, odsread will try to read
     all contents from the first = leftmost (or the only) worksheet (as
     if a range of '' (empty string) was specified).

     If only two arguments are specified, odsread assumes the second
     argument to be WSH and to refer to a worksheet. In that case
     odsread tries to read all data contained in that worksheet.

     The optional last argument REQINTF can be used to override the
     automatic selection by odsread of one interface out of the
     supported ones: Java/ODFtoolkit ('OTK'), Java/jOpenDocument
     ('JOD') or Java/UNO bridge ('UNO').

     Erroneous data and empty cells are set to NaN in NUMARR and turn
     up empty in TXTARR and RAWARR. Date/time values in date/time
     formatted cells are returned as numerical values in OBJ with base
     1-1-000. Note that OpenOfice.org and MS-Excel have different date
     base values (1/1/0000 & 1/1/1900, resp.) and internal
     representation so MS-Excel spreadsheets rewritten into .ods format
     by OpenOffice.org Calc may have different date base values.

     NUMARR and TXTARR are trimmed from empty outer rows and columns,
     so any returned array may turn out to be smaller than requested in
     RANGE.

     When reading from merged cells, all array elements NOT
     corresponding to the leftmost or upper Calc cell will be treated
     as if the "corresponding" Calc cells are empty.

     odsread is just a wrapper for a collection of scripts that find out
     the interface to be used and do the actual reading. For each call
     to odsread the interface must be started and the Calc file read
     into memory. When reading multiple ranges (in optionally multiple
     worksheets) a significant speed boost can be obtained by invoking
     those scripts directly (odsopen / ods2oct [/ parsecell] / ... /
     odsclose).

     Examples:

            A = odsread ('test4.ods', '2nd_sheet', 'C3:AB40');
            (which returns the numeric contents in range C3:AB40 in worksheet
            '2nd_sheet' from file test4.ods into numeric array A)

            [An, Tn, Ra, limits] = odsread ('Sales2009.ods', 'Third_sheet');
            (which returns all data in worksheet 'Third_sheet' in file test4.ods
            into array An, the text data into array Tn, the raw cell data into
            cell array Ra and the ranges from where the actual data came in limits)

          REQINTF)
     Add data in 1D/2D array ARR into sheet WSH in OpenOffice_org Calc
     spreadsheet file FILENAME in cell range RANGE.

     RSTATUS returns 1 if write succeeded, 0 otherwise.

     FILENAME must be a valid .ods OpenOffice.org file name (including
     file name extension). If FILENAME does not contain any directory
     path, the file is saved in the current directory.

     ARR can be any 1D or 2D array containing numerical or character
     data (cellstr) except complex. Mixed numeric/text arrays can only
     be cell arrays.

     WSH can be a number or string. In case of a not yet existing
     OpenOffice.org spreadsheet, the first sheet will be used & named
     according to WSH - no extra empty sheets are created.  In case of
     existing files, some checks are made for existing sheet names or
     numbers, or whether WSH refers to an existing sheet with a type
     other than sheet (e.g., chart).  When new sheets are to be added
     to the spreadsheet file, they are inserted to the right of all
     existing sheets. The pointer to the "active" sheet (shown when
     OpenOffice.org Calc opens the file) remains untouched.

     RANGE is expected to be a regular spreadsheet range.  Data is
     added to the sheet; existing data in the requested range will be
     overwritten.  Array ARR will be clipped at the right and/or bottom
     if its size is bigger than can be accommodated in RANGE.  If ARR
     is smaller than the RANGE allows, it is placed in the top left
     rectangle of RANGE and cell values outside that rectangle will be
     untouched.

     If RANGE contains merged cells, only the elements of ARR
     corresponding to the top or left Calc cells of those merged cells
     will be written, other array cells corresponding to that cell will
     be ignored.

     The optional last argument REQINTF can be used to override the
     automatic selection by odswrite of one interface out of the
     supported ones: Java/ODFtooolkit ('OTK'), Java/jOpenDocument
     ('JOD'), or Java/OpenOffice.org ('UNO').

     odswrite is a mere wrapper for various scripts which find out what
     ODS interface to use (ODF toolkit or jOpenDocument) plus code to
     mimic the other brand's syntax. For each call to odswrite such an
     interface must be started and possibly an ODS file loaded. When
     writing to multiple ranges and/or worksheets in the same ODS file,
     a speed bonus can be obtained by invoking those scripts (odsopen /
     octods / .... / odsclose) directly.

     Example:

            status = odswrite ('test4.ods', 'arr', 'Eight_sheet', 'C3:AB40');
            (which adds the contents of array arr (any type) to range C3:AB40
            in sheet 'Eight_sheet' in file test4.ods and returns a logical
            True (= numerical 1) in status if al went well)

     Divide a heterogeneous 2D cell array into a 2D numeric array and a
     2D cell array containing only strings. Both returned arrays are
     trimmed from empty outer rows and columns.  This function is
     particularly useful for parsing cell arrays returned by functions
     reading spreadsheets (e.g., xlsread, odsread).

     Optional return argument LIM contains two field with the outer
     column and row numbers of NUMARR and TXTARR in the original array
     RAWARR.  Optional input argument LIMITS can either be the
     spreadsheet data limits returned in the spreadsheet file pointer
     struct (field xls.limits or ods.limits), or the file ptr struct
     itself.  If one of these is specified, optional return argument LIM
     will contain the real spreadsheet row & column numbers enclosing
     the origins of the numerical and text data returned in NUMARR and
     TXTARR.

     Examples:

            [An, Tn] = parsecell (Rn);
            (which returns the numeric contents of Rn into array An and the
             text data into array Tn)

 -- Function File: [ RAWARR, XLS, RSTATUS ] = xls2oct (XLS, WSH, RANGE,
          OPTIONS)
     Read data contained within cell range RANGE from worksheet WSH in
     an Excel spreadsheet file pointed to in struct XLS.

     XLS is supposed to have been created earlier by xlsopen in the
     same octave session.

     WSH is either numerical or text, in the latter case it is
     case-sensitive and it may be max. 31 characters long.  Note that
     in case of a numerical WSH this number refers to the position in
     the worksheet stack, counted from the left in an Excel window. The
     default is numerical 1, i.e. the leftmost worksheet in the Excel
     file.

     RANGE is expected to be a regular spreadsheet range format, or ""
     (empty string, indicating all data in a worksheet).  If no range
     is specified the occupied cell range will have to be determined
     behind the scenes first; this can take some time for the
     Java-based interfaces. Be aware that in COM/ActiveX interface the
     used range can be outdated. The Java-based interfaces are more
     reliable in this respect albeit much slower.

     Optional argument OPTIONS, a structure, can be used to specify
     various read modes by setting option fields in the struct to true
     (1) or false (0). Currently recognized option fields are:

    "formulas_as_text"
          If set to TRUE or 1, spreadsheet formulas (if at all present)
          are read as formula strings rather than the evaluated formula
          result values. The default value is 0 (FALSE).

    'strip_array'
          Set the value of this field set to TRUE or 1 to strip the
          returned output array RAWARR from empty outer columns and
          rows. The spreadsheet cell rectangle limits from where the
          data actually came will be updated. The default value is
          FALSE or 0 (no cropping).  When using the COM interface, the
          output array is always cropped.

     If only the first argument XLS is specified, xls2oct will try to
     read all contents from the first = leftmost (or the only)
     worksheet (as if a range of '' (empty string) was specified).

     If only two arguments are specified, xls2oct assumes the second
     argument to be WSH. In that case xls2oct will try to read all data
     contained in that worksheet.

     Return argument RAWARR contains the raw spreadsheet cell data.
     Use parsecell() to separate numeric and text values from RAWARR.

     Optional return argument XLS contains the pointer struct, If any
     data have been read, field XLS.limits contains the outermost
     column and row numbers of the actually returned cell range.

     Optional return argument RSTATUS will be set to 1 if the requested
     data have been read successfully, 0 otherwise.

     Erroneous data and empty cells turn up empty in RAWARR.  Date/time
     values in Excel are returned as numerical values.  Note that Excel
     and Octave have different date base values (1/1/1900 & 1/1/0000,
     resp.)  Be aware that Excel trims RAWARR from empty outer rows &
     columns, so any returned cell array may turn out to be smaller
     than requested in RANGE, independent of field 'formulas_as_text'
     in OPTIONS.  When using COM, POI, or UNO interface, formulas in
     cells are evaluated; if that fails cached values are retrieved.
     These may be outdated depending on Excel's "Automatic calculation"
     settings when the spreadsheet was saved.

     When reading from merged cells, all array elements NOT
     corresponding to the leftmost or upper Excel cell will be treated
     as if the "corresponding" Excel cells are empty.

     Beware: when the COM interface is used, hidden Excel invocations
     may be kept running silently in case of COM errors.

     Examples:

            A = xls2oct (xls1, '2nd_sheet', 'C3:AB40');
            (which returns the numeric contents in range C3:AB40 in worksheet
            '2nd_sheet' from a spreadsheet file pointed to in pointer struct xls1,
            into numeric array A)

            [An, xls2, status] = xls2oct (xls2, 'Third_sheet');

 -- Function File: [ XLS] = xlsclose (XLS, "FORCE")
     Close the Excel spreadsheet pointed to in struct XLS, if needed
     write the file to disk. Based on information contained in XLS,
     xlsclose will determine if the file should be written to disk.

     If no errors occured during writing, the xls file pointer struct
     will be reset and -if COM interface was used- ActiveX/Excel will
     be closed.  However if errors occurred, the file pinter will be
     untouched so you can clean up before a next try with xlsclose().
     Be warned that until xlsopen is called again with the same XLS
     pointer struct, hidden Excel or Java applications with associated
     (possibly large) memory chunks are kept in memory, taking up
     resources.  If (string) argument "FORCE" is supplied, the file
     pointer will be reset regardless, whether the possibly modified
     file has been saved successfully or not. Hidden Excel (COM) or
     OpenOffice.org (UNO) invocations may live on, possibly even
     impeding proper shutdown of Octave.

     FILENAME can be used to write changed spreadsheet files to an
     other file than opened with xlsopen(); unfortunately this doesn't
     work with JXL (JExcelAPI) interface.

     You need MS-Excel (95 - 2010), and/or the Java package => 1.2.8
     plus Apache POI > 3.5 and/or JExcelAPI and/or OpenXLS and/or
     OpenOffice.org or clones installed on your computer + proper
     javaclasspath set, to make this function work at all.

     XLS must be a valid pointer struct made by xlsopen() in the same
     octave session.

     Examples:

            xls1 = xlsclose (xls1);
            (Close spreadsheet file pointed to in pointer struct xls1; xls1 is reset)

 -- Function File: [ FILETYPE, SH_NAMES, FFORMAT] = xlsfinfo (FILENAME
          [, REQINTF])
     Query Excel spreadsheet file FILENAME for some info about its
     contents.

     If FILENAME is a recognizable Excel spreadsheet file, FILETYPE
     returns the string "Microsoft Excel Spreadsheet", or '' (empty
     string) otherwise.

     If FILENAME is a recognizable Excel spreadsheet file, optional
     argument SH_NAMES contains a list (cell array) of sheet names (and
     in case Excel is installed: sheet types) contained in FILENAME, in
     the order (from left to right) in which they occur in the sheet
     stack.

     Optional return value FFORMAT currently returns '' (empty string)
     unless FILENAME is a readable Excel 97-2003 .xls file or an Excel
     2007 .xlsx / .xlsb file in which case FFORMAT is set to
     "xlWorkbookNormal". Excel 95 .xls files can only be read through
     the JXL (JExcelAPI) or UNO (OpenOffice.org) Java-based interfaces.

     If no return arguments are specified the sheet names are echoed to
     the terminal screen; in case of Java interfaces for each sheet the
     actual occupied data range is echoed as well. The occupied cell
     range will have to be determined behind the scenes first; this can
     take some time for the Java-based interfaces.

     If multiple xls interfaces have been installed, REQINTF can be
     specified. This can sometimes be handy, e.g. to get an idea of
     occupied cell ranges in each worksheet using different interfaces
     (due to cached info and/or different treatment of empty but
     formatted cells, each interfaces may give different results).

     For use on OOXML spreadsheets one needs full POI and/or UNO
     support (see xlsopen) and 'poi' or 'uno' needs to be specified for
     REQINTF. For Excel 95 file use 'jxl' or 'uno'.

     Examples:

            exist = xlsfinfo ('test4.xls');
            (Just checks if file test4.xls is a readable Excel file)

            [exist, names] = xlsfinfo ('test4.xls');
            (Checks if file test4.xls is a readable Excel file and return a
             list of sheet names and -types)

 -- Function File: XLS = xlsopen (FILENAME)

     Get a pointer to an Excel spreadsheet in the form of return
     argument (file pointer struct) XLS. After processing the
     spreadsheet, the file pointer must be explicitly closed by calling
     xlsclose().

     Calling xlsopen without specifying a return argument is fairly
     useless!

     To make this function work at all, you need MS-Excel (95 - 2003),
     and/or the Java package >= 1.2.8 plus Apache POI >= 3.5 and/or
     JExcelAPI and/or OpenXLS and/or OpenOffice.org (or clones)
     installed on your computer + proper javaclasspath set. These
     interfaces are referred to as COM, POI, JXL, OXS, and UNO, resp.,
     and are preferred in that order by default (depending on their
     presence).  For OOXML support, in addition to Apache POI support
     you also need the following jars in your javaclasspath:
     poi-ooxml-schemas-3.5.jar, xbean.jar and dom4j-1.6.1.jar (or later
     versions). Later OpenOffice.org versions (UNO) have support for
     OOXML as well.  Excel'95 spreadsheets can only be read by
     JExcelAPI and OpenOffice.org.

     FILENAME should be a valid .xls or xlsx Excel file name (including
     extension). But if you use the COM interface you can specify any
     extension that your installed Excel version can read AND write;
     the same goes for UNO (OpenOffice.org). Using the other Java
     interfaces, only .xls or .xlsx are allowed. If FILENAME does not
     contain any directory path, the file is saved in the current
     directory.

     If READWRITE is set to 0 (default value) or omitted, the Excel file
     is opened for reading. If READWRITE is set to True or 1, an Excel
     file is opened (or created) for reading & writing.

     Optional input argument REQINTF can be used to override the Excel
     interface that otherwise is automatically selected by xlsopen.
     Currently implemented interfaces (in order of preference) are
     'COM' (Excel/COM), 'POI' (Java/Apache POI), 'JXL'
     (Java/JExcelAPI), 'OXS' (Java/OpenXLS), or 'UNO'
     (Java/OpenOffice.org - EXPERIMENTAL!).  In most situations this
     parameter is unneeded as xlsopen automatically selects the most
     useful interface present.

     Beware: Excel invocations may be left running invisibly in case of
     COM errors or forgetting to close the file pointer. Similarly for
     OpenOffice.org which may even prevent Octave from being closed.

     Examples:

            xls = xlsopen ('test1.xls');
            (get a pointer for reading from spreadsheet test1.xls)

            xls = xlsopen ('test2.xls', 1, 'POI');
            (as above, indicate test2.xls will be written to; in this case using Java
             and the Apache POI interface are requested)

          (FILENAME, WSH, RANGE)
 -- Function File: [ NUMARR, TXTARR, RAWARR, LIMITS] = xlsread
          (FILENAME, WSH, RANGE, REQINTF)
     Read data contained in range RANGE from worksheet WSH in Excel
     spreadsheet file FILENAME.  Return argument NUMARR contains the
     numeric data, optional return arguments TXTARR and RAWARR contain
     text strings and the raw spreadsheet cell data, respectively.
     Return argument LIMITS contains the outer column/row numbers of
     the read spreadsheet range where NUMARR, TXTARR and RAWARR have
     come from (remember, xlsread trims outer rows and columns).

     If FILENAME does not contain any directory, the file is assumed to
     be in the current directory. The filename extension (.xls or
     .xlsx) must be included in the file name; when using the COM
     interface all file formats can be read that are supported by the
     locally installed MS-Excel version (e.g., wk1, csv, dbf, etc.).

     RANGE is expected to be a regular spreadsheet range format, or ""
     (empty string, indicating all data in a worksheet).  If no range
     is specified the occupied cell range will have to be determined
     behind the scenes first; this can take some time for the
     Java-based interfaces (but the results may be more reliable than
     that of ActiveX/COM).

     WSH is either numerical or text; in the latter case it is
     case-sensitive and it may be max. 31 characters long.  Note that
     in case of a numerical WSH this number refers to the position in
     the worksheet stack, counted from the left in an Excel window. The
     default is numerical 1, i.e. the leftmost worksheet in the Excel
     file.

     If only the first argument is specified, xlsread will try to read
     all contents (as if a range of '' (empty string) was specified)
     from the first = leftmost (or the only) worksheet

     If only two arguments are specified, xlsread assumes the second
     argument to be RANGE if it is a string argument and contains  a
     ":" or if it is '' (empty string), and in those cases assumes the
     data must be read from the first worksheet (not necessarily
     Sheet1! but the leftmost sheet).

     However, if only two arguments are specified and the second
     argument is numeric or a text string that does not contain a ":",
     it is assumed to be WSH and to refer to a worksheet. In that case
     xlsread tries to read all data contained in that worksheet.

     The optional last argument REQINTF can be used to override the
     automatic interface selection by xlsread out of the supported
     ones: COM/Excel, Java/Apache POI, Java/JExcelAPI, Java/OpenXLS, or
     Java/UNO (OpenOffice.org) (in that -built in- order of preference).
     For reading from OOXML files a value of 'com', 'poi' or 'uno' must
     be specified for REQINTF (see help for xlsopen); for Excel'95
     files use 'com', or if Excel is not installed use 'jxl', 'basic'
     or 'uno' (POI can't read Excel 95 but will try to fall back to
     JXL).  As REQINTF can also be a cell array of strings, one can
     select or exclude one or more interfaces.

     Erroneous data and empty cells are set to NaN in NUMARR and turn
     up empty in TXTARR and RAWARR. Date/time values in Excel are
     returned as numerical values in NUMARR. Note that Excel and Octave
     have different date base values (1/1/1900 & 1/1/0000, resp.).
     Spreadsheet date values lying before 1/1/1900 are returned as
     strings, formatted as they appear in the spreadsheet.  NUMARR and
     TXTARR are trimmed from empty outer rows and columns. Be aware
     that Excel does the same for RAWARR, so any returned array may
     turn out to be smaller than requested in RANGE.

     When reading from merged cells, all array elements NOT
     corresponding to the leftmost or upper Excel cell will be treated
     as if the "corresponding" Excel cells are empty.

     xlsread is just a wrapper for a collection of scripts that find out
     the interface to be used (COM, Java/POI, Java/JXL Java/OXS,
     Java/UNO) and do the actual reading. For each call to xlsread the
     interface must be started and the Excel file read into memory.
     When reading multiple ranges (in optionally multiple worksheets) a
     significant speed boost can be obtained by invoking those scripts
     directly as in: xlsopen / xls2oct [/ parsecell] / ... / xlsclose

     Beware: when using the COM interface, hidden Excel invocations may
     be kept running silently if not closed explicitly.

     Examples:

            A = xlsread ('test4.xls', '2nd_sheet', 'C3:AB40');
            (which returns the numeric contents in range C3:AB40 in worksheet
            '2nd_sheet' from file test4.xls into numeric array A)

            [An, Tn, Ra, limits] = xlsread ('Sales2009.xls', 'Third_sheet');
            (which returns all data in worksheet 'Third_sheet' in file 'Sales2009.xls'
            into array An, the text data into array Tn, the raw cell data into
            cell array Ra and the ranges from where the actual data came in limits)

            numarr = xlsread ('Sales2010.xls', 4, [], {'JXL', 'COM'});
            (Read all data from 4th worksheet in file Sales2010.xls using either JXL
             or COM interface (i.e, exclude POI interface).

 -- Function File: RSTATUS = xlswrite (FILENAME, ARR, WSH, RANGE)
 -- Function File: RSTATUS = xlswrite (FILENAME, ARR, WSH, RANGE,
          REQINTF)
     Add data in 1D/2D array ARR to worksheet WSH in Excel spreadsheet
     file FILENAME in cell range RANGE.

     RSTATUS returns 1 if write succeeded, 0 otherwise.

     FILENAME must be a valid .xls Excel file name (including file name
     extension). If FILENAME does not contain any directory path, the
     file is saved in the current directory.

     ARR can be any 1D or 2D array containing numerical or character
     data (cellstr) except complex. Mixed numeric/text arrays can only
     be cell arrays.

     If only 3 arguments are given, the 3rd is assumed to be a
     spreadsheet range if it contains a ":" or is a completely empty
     string (corresponding to A1:IV65336 for regular .xls or
     A1:XFD1048576 for OOXML .xlsx). The 3rd argument is assumed to
     refer to a worksheet if it is a numeric value or a non-empty text
     string not containing ":"

     WSH can be a number or string (max. 31 chars).  In case of a not
     yet existing Excel file, the first worksheet will be used & named
     according to WSH - the extra worksheets that Excel normally
     creates by default are deleted.  In case of existing files, some
     checks are made for existing worksheet names or numbers, or
     whether WSH refers to an existing sheet with a type other than
     worksheet (e.g., chart).  When new worksheets are to be added to
     the Excel file, they are inserted to the right of all existing
     worksheets. The pointer to the "active" sheet (shown when Excel
     opens the file) remains untouched.

     RANGE is expected to be a regular spreadsheet range.  Data is
     added to the worksheet; existing data in the requested range will
     be overwritten.  Array ARR will be clipped at the right and/or
     bottom if its size is bigger than can be accommodated in RANGE.
     If ARR is smaller than the RANGE allows, it is placed in the top
     left rectangle of RANGE and remaining cell values outside the
     rectangle will be retained.

     If RANGE contains merged cells, only the elements of ARR
     corresponding to the top or left Excel cells of those merged cells
     will be written, other array cells corresponding to that cell will
     be ignored.

     The optional last argument REQINTF can be used to override the
     automatic selection by xlswrite of one interface out of the
     supported ones: 'com' (ActiveX/Excel), 'poi' (Java/Apache POI),
     'jxl' (Java/JExcelAPI), or 'uno' (Java/OpenOffice.org). 'oxs'
     (Java/OpenXLS) is implemented but disabled for writing as it is
     too buggy. For writing to OOXML files (.xlsx) a value of 'com',
     'poi' or 'uno' must be specified for REQINTF. The value of REQINTF
     is case-insensitive. Multiple interfaces can be selected if
     entered as a cell array of strings.

     xlswrite is a mere wrapper for various scripts which find out what
     Excel interface to use (COM, POI, etc) plus code to mimic the other
     brand's syntax. For each call to xlswrite such an interface must be
     started and possibly an Excel file loaded. When writing to multiple
     ranges and/or worksheets in the same Excel file, a speed bonus can
     be obtained by invoking those scripts directly with multiple calls
     to oct2xls (one for each sheet or range) surrounded by one call to
     xlsopen and xlsclose: (xlsopen / octxls / oct2xls / .... /
     xlsclose)

     Examples:

            status = xlswrite ('test4.xls', 'arr', 'Third_sheet', 'C3:AB40');
            (which adds the contents of array arr (any type) to range C3:AB40
            in worksheet 'Third_sheet' in file test4.xls and returns a logical
            True (= numerical 1) in status if al went well)
