set_timestep() [1/2]

template<typename T >

void cntr::herm_matrix< T >::set_timestep	(	int	tstp,
		herm_matrix< T > &	g1
	)

Sets all components at time step tstp to the components of a given herm_matrix.

Purpose

Sets all components of the herm_matrix at time step tstp to the components of given herm_matrix. If tstp = -1, only the Matsubara component will be copied.

Parameters

tstp	The time step at which the components are set.
g1	The herm_matrix from which the time step is copied.
