		type(rt_prop_type), pointer	rtp,
		type(rtp_control_type), pointer	rtp_control

calc_sinvh()

subroutine, public rt_propagation_methods::calc_sinvh	(	type(rt_prop_type), pointer	rtp,
		type(dbcsr_p_type), dimension(:), pointer	matrix_ks,
		type(dbcsr_p_type), dimension(:), pointer	matrix_ks_im,
		type(rtp_control_type), pointer	rtp_control
	)

computes S_inv*H, if needed Sinv*B and S_inv*H_imag and store these quantities to the

exp_H for the real and imag part (for RTP and EMD)

Parameters

rtp	...
matrix_ks	...
matrix_ks_im	...
rtp_control	...
