Detailed Description

Sparse matrix sparse matrix addition using CSR storage format.

rocsparse_csrgeam_nnz computes the total CSR non-zero elements and the CSR row offsets, that point to the start of every row of the sparse CSR matrix, of the resulting matrix C. It is assumed that csr_row_ptr_C has been allocated with size m + 1.

Note

This function is non blocking and executed asynchronously with respect to the host. It may return before the actual computation has finished.

Currently, only rocsparse_matrix_type_general is supported.

Parameters

[in]	handle	handle to the rocsparse library context queue.
[in]	m	number of rows of the sparse CSR matrix \(A\), \(B\) and \(C\).
[in]	n	number of columns of the sparse CSR matrix \(A\), \(B\) and \(C\).
[in]	descr_A	descriptor of the sparse CSR matrix \(A\). Currenty, only rocsparse_matrix_type_general is supported.
[in]	nnz_A	number of non-zero entries of the sparse CSR matrix \(A\).
[in]	csr_row_ptr_A	array of m+1 elements that point to the start of every row of the sparse CSR matrix \(A\).
[in]	csr_col_ind_A	array of nnz_A elements containing the column indices of the sparse CSR matrix \(A\).
[in]	descr_B	descriptor of the sparse CSR matrix \(B\). Currenty, only rocsparse_matrix_type_general is supported.
[in]	nnz_B	number of non-zero entries of the sparse CSR matrix \(B\).
[in]	csr_row_ptr_B	array of m+1 elements that point to the start of every row of the sparse CSR matrix \(B\).
[in]	csr_col_ind_B	array of nnz_B elements containing the column indices of the sparse CSR matrix \(B\).
[in]	descr_C	descriptor of the sparse CSR matrix \(C\). Currenty, only rocsparse_matrix_type_general is supported.
[out]	csr_row_ptr_C	array of m+1 elements that point to the start of every row of the sparse CSR matrix \(C\).
[out]	nnz_C	pointer to the number of non-zero entries of the sparse CSR matrix \(C\). nnz_C can be a host or device pointer.

Return values

rocsparse_status_success	the operation completed successfully.
rocsparse_status_invalid_handle	the library context was not initialized.
rocsparse_status_invalid_size	m, n, nnz_A or nnz_B is invalid.
rocsparse_status_invalid_pointer	descr_A, csr_row_ptr_A, csr_col_ind_A, descr_B, csr_row_ptr_B, csr_col_ind_B, descr_C, csr_row_ptr_C or nnz_C is invalid.
rocsparse_status_not_implemented	rocsparse_matrix_type != rocsparse_matrix_type_general.
