Functions/Subroutines
subroutine, public	calculate_first_density_matrix (scf_env, qs_env)
	can use a variety of methods to come up with an initial density matrix and optionally an initial wavefunction

subroutine, public	calculate_atomic_fock_matrix (matrix_f, atomic_kind_set, qs_kind_set, ounit)
	returns a block diagonal fock matrix.

subroutine, public	calculate_mopac_dm (pmat, matrix_s, has_unit_metric, dft_control, particle_set, atomic_kind_set, qs_kind_set, nspin, nelectron_spin, para_env)
	returns a block diagonal density matrix. Blocks correspond to the mopac initial guess.

Detailed Description

Routines to somehow generate an initial guess.

Function/Subroutine Documentation

subroutine, public qs_initial_guess::calculate_first_density_matrix	(	type(qs_scf_env_type), pointer	scf_env,
		type(qs_environment_type), pointer	qs_env
	)

can use a variety of methods to come up with an initial density matrix and optionally an initial wavefunction

Parameters

scf_env	SCF environment information
qs_env	QS environment

History: 03.2006 moved here from qs_scf [Joost VandeVondele] 06.2007 allow to skip the initial guess [jgh] 08.2014 kpoints [JGH] 10.2019 tot_corr_zeff, switch_surf_dip [SGh]

Note: badly needs to be split in subroutines each doing one of the possible schemes
