Template specialization for Dune::FieldMatrix.
This is a template specialization if the matrix type of the geometry transformation is equal to a Dune::FieldMatrix. The k-th component of the matrix-vector product can then be calculated as a scalar product of the k-th row of the geometry transformation with the gradient on the reference element.
