template<typename T >

void cntr::herm_matrix< T >::smul	(	int	tstp,
		T	weight
	)

Multiplies all component of the herm_matrix with a real scalar.

Purpose

Multiplies all component of the herm_matrix at a given time step tstp with a real scalar weight.

Parameters

tstp	The time step at which the contour object is weighted with a factor.
weight	The weight.
