template<typename T >
T cntr::distance_norm2_les ( int  tstp,
herm_matrix< T > &  g1,
herm_matrix_timestep_view< T > &  g2 
)

Evaluate the Euclidean norm between the lesser components a herm_matrix and herm_matrix_timestep_view at a given time step.

Purpose

Evaluate the Euclidean norm between the lesser components of a herm_matrix \(g_1\) and a herm_matrix_timestep_view ( \(g_2\)) 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

g2

herm_matrix_timestep_view
