Re: lsim() trims time vector in an odd fashion

[rocketsound]

Yes, I get the same results. I noticed this approach works only if the system
supplied to lsim is discrete (i.e. if I replace discreteSystemZOH with
continousSystem in my example code it wont work and I get "invalid time
vector") but I guess this behaviour is correct.

I rewrote the example and shortend it to the relevant lines if this helps
you:

> t_f = 5*1;
> N = 50*1;
> h = t_f/N;
> t_vec = zeros(N + 1, 1);
> for i = 2:length(t_vec)
>     t_vec(i) = t_vec(i - 1) + h;
> end
> u_vec = zeros(N + 1, 1);
> for i = 2:length(u_vec)
>     u_vec(i) = rand;
> end
> x_0 = [1, -0.8];
> 
> sys = c2d(ss([0, 1; 2, -3], [0;  1], [], []), h, 'zoh');
> [y_out, t_out, x_out] = lsim(sys, u_vec, t_vec, x_0);
