Description
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.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.
Return Values
- 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.
