Detailed Description
Convert a sparse CSR matrix into a sparse ELL matrix.
rocsparse_csr2ell_width
computes the maximum of the per row non-zero elements over all rows, the ELL width
, for a given CSR matrix.
- 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 CSR matrix. [in] csr_descr descriptor of the sparse CSR matrix. Currently, only rocsparse_matrix_type_general
is supported.[in] csr_row_ptr array of m+1
elements that point to the start of every row of the sparse CSR matrix.[in] ell_descr descriptor of the sparse ELL matrix. Currently, only rocsparse_matrix_type_general
is supported.[out] ell_width pointer to the number of non-zero elements per row in ELL storage format.
- Return values

is invalid.rocsparse_status_invalid_pointer csr_descr
,csr_row_ptr
