Detailed Description
Convert a sparse ELL matrix into a sparse CSR matrix.
rocsparse_ell2csr_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, for a given ELL matrix. It is assumed that csr_row_ptr
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.
- Parameters
-
[in] handle handle to the rocsparse library context queue. [in] m number of rows of the sparse ELL matrix. [in] n number of columns of the sparse ELL matrix. [in] ell_descr descriptor of the sparse ELL matrix. Currently, only rocsparse_matrix_type_general
is supported.[in] ell_width number of non-zero elements per row in ELL storage format. [in] ell_col_ind array of m
timesell_width
elements containing the column indices of the sparse ELL matrix.[in] csr_descr descriptor of the sparse CSR matrix. Currently, only rocsparse_matrix_type_general
is supported.[out] csr_row_ptr array of m+1
elements that point to the start of every row of the sparse CSR matrix.[out] csr_nnz pointer to the total number of non-zero elements in CSR storage format.
