How does lsim evaluate mimo

I have a multi-input-multi-output statespace model. I want to use lsim(sys,u,t) command to give u as an input.

• If Zgf is my first input of statespace and
• Zgz is the second input of statespace then

u(:,1)= Zgf; 
u(:,2)=Zgr; 
y=lsim(sys,u,t);

is the way to give input to the statespace using lsim? or the other way around?

Thanks!

Have you tested your code? did you get any problem?

Directly from the lsim documentation page:

If sys has three inputs, then u is a t-by-3 array. Each row u(i,:) specifies the input value(s) at the time sample t(i).

So, it is the right way based on your question. Of course, you could also try it to verify :)
