class Intrepid::Basis_HGRAD_WEDGE_C2_FEM< Scalar, ArrayScalar >
Implementation of the default H(grad)-compatible FEM basis of degree 2 on Wedge cell.
Implements Lagrangian basis of degree 2 on the reference Wedge cell. The basis has cardinality 18 and spans a COMPLETE bi-quadratic polynomial space. Basis functions are dual to a unisolvent set of degrees-of-freedom (DoF) defined and enumerated as follows:

- Remarks:
- Ordering of DoFs follows the node order in Wedge<18> topology. Note that node order in this topology does not follow the natural oder of k-subcells where the nodes are located, except for nodes 0 to 5 which coincide with the vertices of the base Wedge<6> topology. As a result, L_0 to L_5 are associated with nodes 0 to 5, but L_6 to L_14 are not associated with edges 0 to 9 in that order. The last three nodes are located on 2-subcells (faces) and follow their order. Thus, L_15, L_16 and L17 are associated with faces 0, 1 and 2 in that order.
