Detailed Description

The B-spline quadrature module.

This module provides functionality for numerical integration (i.e., quadrature rules) over B-spline spaces.

Function/Subroutine Documentation

pure real(wp) function, public m_bspline_quadrature::evaluate	(	type(bsplinequadrature), intent(in)	this,
