# SparseFactor(_:_:_:)

Returns a symbolic factorization of the requested type for a
complex matrix with the given structure, with the supplied options.

```
func SparseFactor(_ type: SparseFactorization_t, _ MatrixComplex: SparseMatrixStructureComplex, _ options: SparseSymbolicFactorOptions) -> SparseOpaqueSymbolicFactorization
```

## Parameters

`type`

The type of factorization to perform.

## Return Value

The requested symbolic factorization of Matrix.

## Discussion

The resulting symbolic factorization may be used for multiple
numerical factorizations with different numerical values but the same
non-zero structure.
