Syntax

sparse_status_t mkl_sparse_qr_reorder (sparse_matrix_t A, struct matrix_descr descr);

Include Files

  • mkl_sparse_qr.h

Description

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

Note

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

Input Parameters

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.

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
