|
|
* It is assumed that \p csr_row_ptr_C has already been filled and that \p csr_val_C and
|
|
* \p csr_col_ind_C are allocated by the user. \p csr_row_ptr_C and the allocation size of
|
|
* \p csr_col_ind_C and \p csr_val_C are defined by the number of non-zero elements of
|
|
* the sparse CSR matrix C. Both can be obtained by using rocsparse_csrgemm_nnz(). The
|
|
* required buffer size for the computation can be obtained by
|
|
* rocsparse_scsrgemm_buffer_size(), rocsparse_dcsrgemm_buffer_size(),
|
|
* rocsparse_ccsrgemm_buffer_size(), and rocsparse_zcsrgemm_buffer_size(), respectively.
|
|
*
|
|
* \note If \f$\alpha == 0\f$, then \f$C = \beta \cdot D\f$ will be computed.
|
|
* \note If \f$\beta == 0\f$, then \f$C = \alpha \cdot op(A) \cdot op(B)\f$ will be computed.
|
|
* \note \f$\alpha == beta == 0\f$ is invalid.
|
|
* \note Currently, only \p trans_A == \ref rocsparse_operation_none is supported.
|
|
* \note Currently, only \p trans_B == \ref rocsparse_operation_none is supported.
|
|
* \note Currently, only \ref rocsparse_matrix_type_general is supported.
|
|
* \note Note that for matrix products with more than 4096 non-zero entries per
|
|
* row, an additional temporary storage buffer is allocated by the algorithm.
|
|
* \note
|
|
* This function supports unsorted CSR matrices as input, while output will be sorted.
|
|
* Note that matrices B and D can only be unsorted up to 4096 non-zero entries
|
|
* per row. If this number is exceeded, \ref rocsparse_status_requires_sorted_storage
|
|
* will be returned.
|
|
