# SparseFactor(_:_:_:_:)

Returns the specified factorization of a sparse matrix of complex float values, using the specified options.

## Declaration

```swift
func SparseFactor(_ type: SparseFactorization_t, _ Matrix: SparseMatrix_Complex_Float, _ options: SparseSymbolicFactorOptions, _ nfoptions: SparseNumericFactorOptions) -> SparseOpaqueFactorization_Complex_Float
```

## Parameters

- `type`: The type of factorization to perform.
- `Matrix`: The matrix to factorize.
- `nfoptions`: Numeric factor options, for example pivoting parameters.

## Return Value

Return Value Factorization of Matrix.
