xbeef_lda_eval()

subroutine, public xc_xbeef::xbeef_lda_eval	(	type(xc_rho_set_type), intent(in)	rho_set,
		type(xc_derivative_set_type), intent(in)	deriv_set,
		integer, intent(in)	grad_deriv,
		type(section_vals_type), pointer	xbeef_params
	)

evaluates the beef exchange functional for lda

Parameters

rho_set	the density where you want to evaluate the functional
deriv_set	place where to store the functional derivatives (they are added to the derivatives)
grad_deriv	degree of the derivative that should be evaluated, if positive all the derivatives up to the given degree are evaluated, if negative only the given degree is calculated
xbeef_params	input parameters (scaling)
