)Expand description
Get the numerical quadrature information for the given element type
elementType and integration rule integrationType (e.g. “Gauss4” for a
Gauss quadrature suited for integrating 4th order polynomials).
integrationPoints contains the u, v, w coordinates of the G integration
points in the reference element: [g1u, g1v, g1w, …, gGu, gGv, gGw].
integrationWeigths contains the associated weights: [g1q, …, gGq].
