## Overview\abstract 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.
