## ◆ incr_timestep() [2/6]

template<typename T >
 void cntr::herm_matrix_timestep_view< T >::incr_timestep ( herm_matrix_timestep_view< T > & g, T alpha )

Increase the value of the herm_matrix_timestep_view for $$\alpha g(t)$$.

Purpose

Increase the value of herm_matrix_timestep_view for a value of $$\alpha g(t)$$, where $$g(t)$$ is a herm_matrix_timestep_view and $$\alpha$$ is a template argument If $$t>-1$$ then ret,les,tv components are set, otherwise mat. Works for scalar or square-matrix contour objects.

Parameters
 g The template argument which is added alpha Constant template argument multiplication factor
