Detailed Description

This function converts the sparse matrix in CSC format into a column-oriented dense matrix.

Note

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

This routine supports execution in a hipGraph context.

Parameters

[in]	handle	- handle to the rocSPARSE library context queue.
[in]	m	- number of rows of the column-oriented dense matrix A.
[in]	n	- number of columns of the column-oriented dense matrix A.
[in]	descr	- the descriptor of the column-oriented dense matrix A. The supported matrix type is rocsparse_matrix_type_general and also any valid value of the rocsparse_index_base.
[in]	csc_val	- array of nnz ( = csc_col_ptr[n] - csc_col_ptr[0] ) non-zero elements of matrix A.
[in]	csc_col_ptr	- integer array of n+1 elements that contains the start of every column and the end of the last column plus one.
[in]	csc_row_ind	- integer array of nnz ( = csc_col_ptr[n] - csc_col_ptr[0] ) column indices of the non-zero elements of matrix A.
[out]	A	- array of dimensions (ld, n).
[out]	ld	- leading dimension of column-oriented dense matrix A.

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, or ld is invalid.
rocsparse_status_invalid_pointer	A, csc_val, csc_col_ptr, or csc_row_ind pointer is invalid.
