Detailed Description

template<int dim, int fe_degree, int n_q_points_1d, int n_components, typename Number>
struct internal::FEEvaluationImplTransformToCollocation< dim, fe_degree, n_q_points_1d, n_components, Number >

This struct performs the evaluation of function values, gradients and Hessians for tensor-product finite elements. This a specialization for symmetric basis functions about the mid point 0.5 of the unit interval with the same number of quadrature points as degrees of freedom. In that case, we can first transform the basis to one that has the nodal points in the quadrature points (i.e., the collocation space) and then perform the evaluation of the first and second derivatives in this transformed space, using the identity operation for the shape values.
