# quadrature_integrate_options

## Declaration

```swift
struct quadrature_integrate_options
```

## Overview

Overview Integration options Can be 0, 15, 21, 31, 41, 51, 61. 0 maps to the default 21. Used by the QAG integrator only. Other integrators ignore this value. If a workspace is provided, this value is ignored, and the number of intervals is limited by workspace_size. The QNG integrator doesn’t require a workspace. The QAG integrator requires at least max_intervals * QUADRATURE_INTEGRATE_QAG_WORKSPACE_PER_INTERVAL bytes in workspace. The QAGS integrator requires at least max_intervals * QUADRATURE_INTEGRATE_QAGS_WORKSPACE_PER_INTERVAL bytes in workspace.
