Detailed Description
template<class Scalar, class ArrayScalar>
class Intrepid::Basis_HGRAD_HEX_Cn_FEM< Scalar, ArrayScalar >
Implementation of the default H(grad)-compatible FEM basis of degree 2 on Hexahedron cell.
Implements Lagrangian basis of degree n on the reference Hexahedron cell. The basis has cardinality (n+1)^3 and spans a COMPLETE polynomial space. Basis functions are dual to a unisolvent set of degrees-of-freedom (DoF) defined lexicographically on an array of input points.

Evaluation of a FEM basis on a reference Hexahedron cell.
Returns values of operatorType acting on FEM basis functions for a set of points in the reference Hexahedron cell. For rank and dimensions of I/O array arguments see Section MD array template arguments for basis methods.
- Parameters:
-
outputValues [out] - rank-2 or 3 array with the computed basis values inputPoints [in] - rank-2 array with dimensions (P,D) containing reference points operatorType [in] - operator applied to basis functions
