mkl_sparse_qr

Reordering step of SPARSE QR solver.

Syntax

sparse_status_t mkl_sparse_qr_reorder (sparse_matrix_t A, struct matrix_descr descr);

The mkl_sparse_qr_reorder routine performs ordering and symbolic analysis of matrix A.

Currently, mkl_sparse_qr_reorder supports only general structure and CSR format for the input matrix.

A: Handle containing a sparse matrix in an internal data structure.
descr: Structure specifying sparse matrix properties. Only the parameters listed here are currently supported.

SPARSE_STATUS_SUCCESS: The operation was successful.
SPARSE_STATUS_NOT_INITIALIZED: The routine encountered an empty handle or matrix array.
SPARSE_STATUS_ALLOC_FAILED: Internal memory allocation failed.
SPARSE_STATUS_INVALID_VALUE: The input parameters contain an invalid value.
SPARSE_STATUS_EXECUTION_FAILED: Execution failed.
SPARSE_STATUS_INTERNAL_ERROR: An error in algorithm implementation occurred.
SPARSE_STATUS_NOT_SUPPORTED: The requested operation is not supported.
