Detailed Description

template<class D, class R, unsigned int k>
class Dune::Pk1DLocalBasis< D, R, k >

Lagrange shape functions of arbitrary order on the 1D reference triangle.

Lagrange shape functions of arbitrary order have the property that $\hat\phi^i(x_j) = \delta_{i,j}$ for certain points $x_j$ .

Template Parameters

D	Type to represent the field in the domain.
R	Type to represent the field in the range.
k	Polynomial order.
