This function converts the sparse matrix in CSR format into a dense matrix.

Parameters:

  • m – [in] number of rows of the dense matrix A.

  • n – [in] number of columns of the dense matrix A.

  • descr – [in] the descriptor of the dense matrix A, the supported matrix type is aoclsparse_matrix_type_general. Base index from the descriptor is used in the conversion process.

  • csr_val – [in] array of size at least nnz nonzero elements of matrix A.

  • csr_row_ptr – [in] CSR row pointer array of size (m +1).

  • csr_col_ind – [in] An array of CSR column indices of at least nnz column indices of the nonzero elements of matrix A.

  • A – [out] array of dimensions (lda, n)

  • ld – [in] leading dimension of dense array A.

  • order – [in] memory layout of a dense matrix A. It can be either aoclsparse_order_column or aoclsparse_order_row.

Return values:

  • aoclsparse_status_success – the operation completed successfully.

  • aoclsparse_status_invalid_size – m or n or ld is invalid.

  • aoclsparse_status_invalid_pointer – A, csr_val, csr_row_ptr, or csr_col_ind pointers are invalid.
