# SparseOpaqueFactorization_Double

A structure that represents the factorization of a matrix of double-precision, floating-point values.

## Declaration

```swift
struct SparseOpaqueFactorization_Double
```

## Mentioned in

Solving systems using direct methods

## Overview

Overview Use the SparseCleanup(_:) function to free resources that these objects hold. An object can be in one of the following states:  |   |   |   |
