Detailed Description

template<typename Mat, typename RF, std::size_t size>
struct Dune::PDELab::SingleDerivativeComputationHelper< Mat, RF, size >

Helper class to compute a single derivative of scalar basis functions.

Template Parameters

Mat	The matrix type of the geometry transformation.
RF	The underlying field type of Mat, needed especially for the template specialization.
size	The size of Mat, needed especially for the template specialization

The k-th derivative of scalar basis functions is calculated from the matrix-vector product of the geometry transformation and the gradient on the reference element by picking out the k-th component.
