Re: Problem using Evaluate[] inside a Plot command. 5.1


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
