Implementation of a sequential dense matrix class based on PETSC. All the functionality is actually in the base class, except for the calls to generate a sequential dense matrix. This is possible since PETSc only works on an abstract matrix type and internally distributes to functions that do the actual work depending on the actual matrix type (much like using virtual functions). Only the functions creating a matrix of specific type differ, and are implemented in this particular class.
Definition at line 49 of file petsc_full_matrix.h.
Declare type for container size.
Definition at line 56 of file petsc_full_matrix.h.
| FullMatrix< number >::FullMatrix | ( | ) |
Default constructor. Create an empty matrix.
Definition at line 27 of file petsc_full_matrix.cc.
| FullMatrix< number >::FullMatrix | ( | const size_type | m, |
| const size_type | n | ||
| ) |
Create a full matrix of dimensions m times n.
Definition at line 33 of file petsc_full_matrix.cc.
| void FullMatrix< number >::reinit | ( | const size_type | m, |
| const size_type | n | ||
| ) |
Throw away the present matrix and generate one that has the same properties as if it were created by the constructor of this class with the same argument list as the present function.
Definition at line 40 of file petsc_full_matrix.cc.
|
virtual |
Return a reference to the MPI communicator object in use with this matrix. Since this is a sequential matrix, it returns the MPI_COMM_SELF communicator.
Implements PETScWrappers::MatrixBase.
Definition at line 70 of file petsc_full_matrix.cc.
|
private |
Do the actual work for the respective reinit() function and the matching constructor, i.e. create a matrix. Getting rid of the previous matrix is left to the caller.
