Detailed Description

template<class FunctionSpace, bool hierarchicalOrdering = false>
class Dune::Fem::LegendreShapeFunctionSet< FunctionSpace, hierarchicalOrdering >

a Dune::Fem::ShapeFunctionSet of Legendre ansatz polynomials

Note

The range field type used in the evaluation is fixed to double.

This shape function set can only be used with cubic reference elements.

Template Parameters

FunctionSpace	(scalar) function space
hierarchicalOrdering	(bool) if true shape functions are ordered according to their polynomial order
