Detailed Description

template<typename DGBF>
class Dune::Functions::DiscreteGlobalBasisFunctionDerivative< DGBF >

Derivative of a DiscreteGlobalBasisFunction

Function returning the derivative of the given DiscreteGlobalBasisFunction with respect to global coordinates.

The function handles the mapping of coefficient blocks and basis function values to range entries analogously to the DiscreteGlobalBasisFunction. This mapping is implemented with the same algorithm but with values replace by jacobian.

Template Parameters
DGBFinstance of the DiscreteGlobalBasisFunction this is a derivative of

◆ operator()()

template<typename DGBF >
Range Dune::Functions::DiscreteGlobalBasisFunctionDerivative< DGBF >::operator() ( const Domain &  x) const
inline

Evaluate the discrete grid-function derivative in global coordinates.

Warning
This has to find the element that the evaluation point is in. It is therefore very slow.
