Implementation of the default H(div)compatible RaviartThomas basis of arbitrary degree on Triangle cell.
Implements nodal basis of degree n (n>=1) on the reference Triangle cell. The basis has cardinality n(n+2) and spans an INCOMPLETE polynomial space of degree n. Basis functions are dual to a unisolvent set of degreesoffreedom (DoF) defined and enumerated as
If the pointType argument to the constructor specifies equispaced points, then the edge points will be equispaced on each edge and the interior points equispaced also. If the pointType argument specifies warpblend points, then GaussLobatto points of order n are chosen on each edge and the interior of warpblend lattice of order n+1 is chosen for the interior points.
