Detailed Description

template<typename T_ansatzsp, typename T_testsp, typename T_val>
class HLIB::TInvarBasisQuadHCAGenFn< T_ansatzsp, T_testsp, T_val >

Optimises evaluation of basis function for quadrature points under the assumption, that they are invariant with respect to translation and scaling, e.g. can be precomputed on reference triangles.
