Detailed Description

template<std::size_t order, std::size_t dim, typename Data_T = double>
class WTensor< order, dim, Data_T >

Implements a tensor that has the same number of components in every direction.

Template Parameters:

order	The order of the tensor.
dim	The dimension of the tensor, i.e. the number of components in each direction.
Data_T	The datatype of the components, double by default.

Notes:

The dimension may never be 0.

Notes:

The type Data_T may not throw exceptions on construction, destruction or during any assignment operator.

Access to specific elements of the tensor can be achieved in 2 ways:

• operator (), whose number of parameters matches the template parameter order.
• operator [], whose parameter is either an array or a std::vector of appropriate size.

Notes:

The datatype of the array or std::vector can be any type castable to std::size_t.

Notes:

There is no bounds checking for the array version of operator [].

Notes:

Operator () is not supported for orders larger than 6.

Examples:

• Construct a tensor of order 2 and dimension 3 (i.e. a 3x3-Matrix):

  WTensor< 2, 3 > w;

• Change Element (2,0) to 4.0:

  w( 2, 0 ) = 4.0;

• Construct a 4D-vector:

  WTensor< 1, 4 > v;

• Access v at position 2:

  v( 2 ) = ...;

  std::vector< int > i( 1, 2 ); v[ i ] = ...;
