Hi.

I'm trying to get the polynomials A(q) and B(a)for an ARX model, in the MIMO case. Matlab function "arx" works only for SISO case, so I'm trying with "iv4". When I have y=y1 and u=[u1 u2] it works, but for y=[y1 y2] and u=[u1 u2] I didn't get success. Can anybody help me with this function or inform another one?

Thanks.

ARX does work for MIMO case. So does IV4. Can you post an example?
