After creating a system "sys" using 'feedback' command, I'm trying to extract A_sys,B_sys,C_sys matrices for this new system.

I can view them by using ss(sys), but I'd like to use them for further math in my code.

Is there a way to extract them out ?

There's a command called ssdata that you can use.

[A_sys,B_sys,C_sys,D_sys] = ssdata(sys)

That should work.
