Detailed Description
template<typename DGBF>
class Dune::Functions::DiscreteGlobalBasisFunctionDerivative< 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.

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.
