distance_norm2_tv() [4/9]

template<typename T >

T cntr::distance_norm2_tv	(	int	tstp,
		herm_matrix_timestep< T > &	g1,
		herm_matrix_timestep< T > &	g2
	)

Evaluate the Euclidean norm between the left-mixing components a herm_matrix_timestep and herm_matrix_timestep at a given time step.

Purpose

Evaluate the Euclidean norm between the left-mixing components of a herm_matrix_timestep \(g_1\) and a herm_matrix_timestep ( \(g_2\)) at a given time step (tstp). The norm is not normalized per elements, but it is the summention of all the elements.

Parameters

tstp	time step
g1	herm_matrix_timestep
g2	herm_matrix_timestep
