# SparseFactor(_:_:_:)

Returns the factorization of a sparse matrix of complex float values corresponding to the supplied symbolic factorization, using the specified options.

## Declaration

```swift
func SparseFactor(_ SymbolicFactor: SparseOpaqueSymbolicFactorization, _ Matrix: SparseMatrix_Complex_Float, _ nfoptions: SparseNumericFactorOptions) -> SparseOpaqueFactorization_Complex_Float
```

## Parameters

- `SymbolicFactor`: A symbolic factorization, as returned by a call of the form SymbolicFactor = SparseFactor(Matrix.structure).
- `Matrix`: The matrix to factorize.
- `nfoptions`: Numeric factor options, for example pivoting parameters.

## Return Value

Return Value Factorization of Matrix.
