Hey guys,
How to generate random stable state space model? A=rand(100,100) with eig(A)<0.
Thanks, Rebbecca

Yes, you can!
>> A = rss(100)

Does rss guarantee stability? The question was for a random stable system.

Doesn't quite answer the question.
rss allows for integrators in the model, so the result may be unstable.

Hello,
I would like to generate a random NON-linear state space system. Is there a command for that or shall i generate a linear one and then modify it to make it nonlinear (add square, sine, cosine, etc.) ? And how to ensure the generated system is a stable system ?
Appreciate your help.
Thanks Firas
