Functions/Subroutines
subroutine, public	pao_guess_initial_potential (qs_env, iatom, block_v)
	Makes an educated guess for the initial potential based on positions of neighboring atoms.
subroutine, public	pao_calc_gaussian (basis_set, block_v, block_d, rab, lpot, beta, weight, min_shell, max_shell, min_l, max_l)
	Calculates potential term of the form r**lpot * Exp(-beta*r**2) One needs to call init_orbital_pointers(lpot) before calling pao_calc_gaussian().

pao_calc_gaussian()

subroutine, public pao_potentials::pao_calc_gaussian	(	type(gto_basis_set_type), pointer	basis_set,
		real(dp), dimension(:, :), intent(out), optional	block_v,
		real(dp), dimension(:, :, :), intent(out), optional	block_d,
		real(dp), dimension(3)	rab,
		integer, intent(in)	lpot,

		integer, intent(in), optional	min_shell,
		integer, intent(in), optional	max_shell,
		integer, intent(in), optional	min_l,
		integer, intent(in), optional	max_l
	)

Calculates potential term of the form r**lpot * Exp(-beta*r**2) One needs to call init_orbital_pointers(lpot) before calling pao_calc_gaussian().

Parameters

basis_set	...
block_V	potential term that is returned
block_D	derivative of potential term wrt to Rab
Rab	...
lpot	polynomial prefactor, r**lpot
beta	exponent of the Gaussian
weight	...
min_shell	...
max_shell	...
min_l	...
max_l	...
