linres_solver()

subroutine, public qs_linres_methods::linres_solver	(	type(qs_p_env_type)	p_env,
		type(qs_environment_type), pointer	qs_env,
		type(cp_fm_type), dimension(:), intent(in)	psi1,

		type(cp_fm_type), dimension(:), intent(in)	psi0_order,
		integer, intent(in)	iounit,
		logical, intent(out)	should_stop
	)

scf loop to optimize the first order wavefunctions (psi1) given a perturbation as an operator applied to the ground state orbitals (h1_psi0) psi1 is defined wrt psi0_order (can be a subset of the occupied space) The reference ground state is defined through qs_env (density and ground state MOs) psi1 is orthogonal to the occupied orbitals in the ground state MO set (qs_envmos)

Parameters

p_env	...
qs_env	...
psi1	...
h1_psi0	...
psi0_order	...
