Detailed Description

template<typename GV, int k, typename R = double>
class Dune::Functions::LagrangeDGPreBasis< GV, k, R >

PreBasis implementation for a Lagrangean-DG finite element space.

Template Parameters

GV	The grid view that the FE basis is defined on
k	The order of ansatz functions; -1 means 'order determined at run-time'
R	Range type used for shape function values

Constructor & Destructor Documentation

template<typename GV , int k, typename R = double>

Dune::Functions::LagrangeDGPreBasis< GV, k, R >::LagrangeDGPreBasis ( const GridView & gv )

inline

Constructor for a given grid view object.

This constructor requires that the order is given at compile-time using k>=0

template<typename GV , int k, typename R = double>

Dune::Functions::LagrangeDGPreBasis< GV, k, R >::LagrangeDGPreBasis	(	const GridView &	gv,
		unsigned int	order
	)

inline

Constructor for a given grid view object.

This constructor has to be used to set the order dynamically which is enables using k<0.
