> Are they not both valid norms and operator norms? >I think that they should probably be invoked by opnorm(sys, p=2) The system 2-norms aren't induced norms (and not submultiplicative),...

> Matlab understands norm(G), norm(G,2) and norm(G, inf) which is what we currently have.. This is certainly something to take into consideration, but I don't think we should give it...

The toolbox only supports the case of infinite horizon and constant system dynamics, which can be solved as an algebraic Riccati equation. Time-varying LQR is more involved. In continuous time...

> So for the above suggestion we go with u(t) / u(uout, t) then. Yes, I think that is the right way to go. But we would need some `sim_statefeedback`/`sim_statefb`...
