* \brief
|
|
* This function converts the general BSR sparse matrix \f$A\f$ to another general BSR sparse matrix \f$C\f$.
|
|
*
|
|
* \details
|
|
* \p rocsparse_gebsr2gebsr converts a general BSR matrix \f$A\f$ into a general BSR matrix \f$C\f$. The input
|
|
* and output matrices can have different row and column block dimensions. The input matrix \f$A\f$ is assumed
|
|
* to be allocated such that array \p bsr_row_ptr_A has length \p mb+1, \p bsr_col_ind_A has length \p nnzb, and
|
|
* \p bsr_val_A has length \p nnzb*row_block_dim_A*col_block_dim_A. The output matrix \f$C\f$ is assumed to be
|
|
* allocated such that array \p bsr_row_ptr_C has length \p mb_C+1, \p bsr_col_ind_C has length \p nnzb_C, and
|
|
* \p bsr_val_C has length \p nnzb_C*row_block_dim_C*col_block_dim_C where:
|
|
* \f[
|
|
* m = mb * row\_block\_dim\_A \\
|
|
* n = nb * col\_block\_dim\_A
|
|
* \f]
|
|
* and
|
|
* \f[
|
|
* mb\_C = (m + row\_block\_dim\_C - 1) / row\_block\_dim\_C \\
|
|
* nb\_C = (n + col\_block\_dim\_C - 1) / col\_block\_dim\_C
|
|
* \f]
|
|
* The number of non-zero blocks in the output sparse \f$C\f$ matrix (i.e. \p nnzb_C) is computed using
|
|
* \ref rocsparse_gebsr2gebsr_nnz() which also fills in the \p bsr_row_ptr_C array.
|
|
*
|
|
* Converting from a sparse general BSR matrix to a sparse general BSR matrix requires three steps. First,
|
|
* call \ref rocsparse_sgebsr2gebsr_buffer_size "rocsparse_Xgebsr2gebsr_buffer_size()"
|
|
* to determine the size of the required temporary storage buffer. After this has been determined,
|
|
* allocate this buffer. Also allocate the \p bsr_row_ptr_C array to have length
|
|
* \p mb_C+1 and pass it to the function \ref rocsparse_gebsr2gebsr_nnz. This will fill the \p bsr_row_ptr_C
|
|
* array and also compute the total number of non-zero blocks in the general BSR output \f$C\f$ matrix. Now that
|
|
* the total number of non-zero blocks is known, allocate the \p bsr_col_ind_C and \p bsr_val_C arrays.
|
|
* Finally, call \p rocsparse_gebsr2gebsr to complete the conversion. After the conversion is complete,
|
|
* the temporary storage buffer can be deallocated. See the example below.
|
|
*
