Public Member Functions | |
| vandermonde_matrix () | |
| The default constructor. Does not allocate any memory. | |
| vandermonde_matrix (vcl_size_t rows, vcl_size_t cols) | |
| Creates the matrix with the given size. | |
| void | resize (vcl_size_t sz, bool preserve=true) |
| Resizes the matrix. Existing entries can be preserved. | |
| handle_type const & | handle () const |
| Returns the OpenCL handle. | |
| viennacl::vector< SCALARTYPE, ALIGNMENT > & | elements () |
| Returns an internal viennacl::vector, which represents a Vandermonde matrix elements. | |
| viennacl::vector< SCALARTYPE, ALIGNMENT > const & | elements () const |
| vcl_size_t | size1 () const |
| Returns the number of rows of the matrix. | |
| vcl_size_t | size2 () const |
| Returns the number of columns of the matrix. | |
| vcl_size_t | internal_size () const |
| Returns the internal size of matrix representtion. Usually required for launching OpenCL kernels only. | |
| entry_proxy< SCALARTYPE > | operator() (vcl_size_t row_index) |
| Read-write access to a base element of the matrix. | |
| SCALARTYPE | operator() (vcl_size_t row_index, vcl_size_t col_index) const |
| Read access to a element of the matrix. | |
A Vandermonde matrix class.
| SCALARTYPE | The underlying scalar type (either float or double) |
| ALIGNMENT | The internal memory size is given by (size()/ALIGNMENT + 1) * ALIGNMENT. ALIGNMENT must be a power of two. Best values or usually 4, 8 or 16, higher values are usually a waste of memory. |
| typedef scalar<typename viennacl::tools::CHECK_SCALAR_TEMPLATE_ARGUMENT<SCALARTYPE>::ResultType> value_type |
