Hello,

I wonder if someone has already used the N4SID Gui for a MIMO system case identifacation.

How can I express the Data that i already have to have a state space model describing the dynamics of my MIMO system? is it the same way in the case of SISO case?

Thank you for your assistance.

Cordially

n4sid accepts either frd or idfrd, these are built-in matlab functions. In creation of the idfrd or frd object, you define the number of input and outputs. MIMO and SISO cases are identical.
