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.
