Detailed Description

template<typename GV, int k, typename R>
class Dune::Functions::LagrangePreBasis< GV, k, R >

A pre-basis for a PQ-lagrange bases with given order.

Template Parameters

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

Note

This only works for certain grids. The following restrictions hold

If k is no larger than 2, then the grids can have any dimension
If k is larger than 3 then the grid must be two-dimensional
If k is 3, then the grid can be 3d if it is a simplex grid
