# SparseNumericFactorOptions

A structure that contains options that affect the numerical stage of a sparse factorization.

## Declaration

```swift
struct SparseNumericFactorOptions
```

## Overview

Overview SparseNumericFactorOptions supports the following types of scaling:  |   |   |  Note that the system clamps pivotTolerance to range [0,0.5].
