Here the point is to give some lines of code illustrating what are the H2 and Hinf norms of LTI systems.



In that sense, it is also illustrated that the H2 norm is smooth in the space of the system parameters, whereas the Hinf norm is non-smooth locally Lipschitz (since it is a min-max problem, thus prone to the waterbed effect ).-or a thorough descr iption of the norms, see the Chapter 4 of Robust and Optimal Control, Zhou, Glover, Doyle 1996.
