## ◆ incr_timestep() [5/6]

template<typename T>
template<typename T >
 void cntr::herm_matrix_timestep_view< T >::incr_timestep ( herm_matrix_timestep_view< T > & g, CPLX 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 complex number If $$t>-1$$ then ret,les,tv components are set, otherwise mat. Works for scalar or square-matrix contour objects.

Parameters
 g The herm_matrix_timestep_view which is added alpha Constant multiplication factor
