# SparseFactor(_:_:_:)

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

## Declaration

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

## Parameters

- `type`: The type of factorization to perform.

## Return Value

Return Value The requested symbolic factorization of Matrix.

## Discussion

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