compute_linear_transformation()

template<int dim, int spacedim, int N>

Quadrature<spacedim> compute_linear_transformation	(	const Quadrature< dim > &	quadrature,
		const std::array< Point< spacedim >, N > &	vertices
	)

Given a dim-dimensional quadrature formula to integrate over vertices, returns a spacedim-dimensional quadrature formula to integrate in the real space.

This function is a generalization of compute_affine_transformation().

Template Parameters

dim	The template dimension of the original Quadrature formula.
spacedim	The template dimension of the resulting Quadrature formula on the real space
N	The number of vertices of the element we need to integrate on.

Parameters

quadrature	A Quadrature<dim> formula
vertices	The std::array with N vertices you wish to integrate on.

Returns

Quadrature<spacedim>object in the real space
