set_timestep_zero()

template<typename T >

void cntr::herm_matrix< T >::set_timestep_zero

(

int

tstp

)

Sets all components at time step tstp to zero.

Purpose

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

Parameters

tstp	The time step at which the components are set to zero.
