## ◆ 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.
