Input Parameters
- policy
-
C_INT.
Specify memory utilization policy for optimization routine using these types:
SPARSE_MEMORY_NONE
Routine can allocate memory only for auxiliary structures (such as for workload balancing); the amount of memory is proportional to vector size.
SPARSE_MEMORY_AGGRESSIVE
Default.
Routine can allocate memory up to the size of matrix A for converting into the appropriate sparse format.
Output Parameters
- A
-
SPARSE_MATRIX_T.
Handle containing internal data.
- stat
-
INTEGER
Value indicating whether the operation was successful or not, and 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.
