Forced step response of a signal

39 views (last 30 days)
I'm pretty new to matlab and I'm having a hard time understanding how the signals &systems part works. All I have to do is find the step response of a system, both a "normal" response and a "forced " response, while having initial conditions. I searched this forum and I couldn't really find something similar. Maybe because it's an easy one but I don't know.
I tried using 'step' but I didn't know how to use the initial conditions with it. Also, I found out 'initial' and I tried using it but it didn't really work out either.

I recommend you look into lsim() function, which is a lot more flexible than the step() or impulse() functions, and would be useful for the future as well.

Thank you, got it right finally (with lsim)

You can set the initial values of the step using stepDataOptions:
What was the problem with initial ?
