Detailed Description

Convert a sparse HYB matrix into a sparse CSR matrix.

rocsparse_hyb2csr_buffer_size returns the size of the temporary storage buffer required by rocsparse_shyb2csr(), rocsparse_dhyb2csr(), rocsparse_chyb2csr() and rocsparse_dhyb2csr(). The temporary storage buffer must be allocated by the user.

Parameters

[in]	handle	handle to the rocsparse library context queue.
[in]	descr	descriptor of the sparse HYB matrix. Currently, only rocsparse_matrix_type_general is supported.
[in]	hyb	sparse matrix in HYB format.
[in]	csr_row_ptr	array of m+1 elements that point to the start of every row of the sparse CSR matrix.
[out]	buffer_size	number of bytes of the temporary storage buffer required by rocsparse_shyb2csr(), rocsparse_dhyb2csr(), rocsparse_chyb2csr() and rocsparse_zhyb2csr().

Return values

rocsparse_status_success	the operation completed successfully.
rocsparse_status_invalid_handle	the library context was not initialized.
rocsparse_status_invalid_pointer	descr, hyb, csr_row_ptr or buffer_size pointer is invalid.
rocsparse_status_internal_error	an internal error occurred.
rocsparse_status_not_implemented	rocsparse_matrix_type != rocsparse_matrix_type_general.
