Description
You can use this routine to enable a pivot strategy in the case of an ill-conditioned matrix.
Input Parameters
A
Handle containing a sparse matrix in an internal data structure.
hint
Value specifying whether to use pivoting.
The only value currently supported is SPARSE_QR_WITH_PIVOTS, which enables the use of a pivot strategy for an ill-conditioned matrix.
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
