Detailed Description

template<typename T, typename X>
class Dune::PDELab::DiscreteGridFunctionGradient< T, X >

convert a single component function space with a grid function representing the gradient

The function values should be single-component vectors. The Gradien will be a dimDomain-component function.

Template Parameters

T	Type of GridFunctionSpace. The LocalBasis must provide the evaluateJacobian() method.
X	Type of coefficients vector
