Hi Nasser, Maybe Evaluate[OutputResponse[sys,UnitStep[t], t]] is returning a value which needs to be Evaluate[]d again before it can be plotted? I've never had your problem (don't even have the control toolbox), but maybe Plot[{t2, Evaluate[Evaluate[OutputResponse[sys,UnitStep[t], t]]]}, {t, 0, 3}, PlotRange -> All] might work? Your error message, "plot::plnr: .... is not a machine-size real number at t=...." usually indicates the need to Evaluate[] one of the Plot[] arguments. Good luck, Daniel
