evaluate()

void FunctionalGGA::evaluate ( int  N, std::vector< const double * >  n, std::vector< const double * >  sigma, std::vector< const double * >  lap, std::vector< const double * >  tau, double *  E, std::vector< double * >  E_n, std::vector< double * >  E_sigma, std::vector< double * >  E_lap, std::vector< double * >  E_tau  ) const

virtual

The thread launchers and gpu kernels for all GGAs are generated by this function using the template specializations of GGA_calc, GGA_eval Note that lap and taus are unused by GGAs

Implements Functional.
