set_tk_from_mat()

template<typename T >

void cntr::set_tk_from_mat	(	herm_matrix< T > &	G,
		int	kt
	)

Set components of herm_matrix at t=0,1,..kt from the Matsubara component.

Purpose

Set components of herm_matrix at t=0,1,..kt (retarded,lesser,left-mixing components) from the Matsubara component.

Note

This function put contant values for t=0,1,..kt for each components.

Parameters

G	herm_matrix to be modified
kt	the time up to which the values are set.
