calculates a functional from libxc and its derivatives
WARNING: In the subroutine libxc_lsd_calc, it could be that the ordering for the 1st index of v2lapltau, v2rholapl, v2rhotau, v2sigmalapl and v2sigmatau is not correct. For the moment it does not matter since the calculation of the 2nd derivatives for meta-GGA functionals is not implemented in CP2K.
| logical function, public xc_libxc::libxc_check_existence_in_libxc | ( | type(section_vals_type), intent(in), pointer | libxc_params | ) |
