mkl_sparse_qr

Reordering step of SPARSE QR solver.

Syntax

stat = mkl_sparse_qr_reorder ( A, 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

SPARSE_MATRIX_T

Handle containing a sparse matrix in an internal data structure.

descr

MATRIX_DESCR

Structure specifying sparse matrix properties. Only the parameters listed here are currently supported.

stat

INTEGER

Value indicating whether the operation was successful, and if not, why:

`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.
