Thread Subject: Changing ARX model to State Space model

Hi, does anyone know how to change an ARX model to a State Space model?

If you ARX model was created using system identification toolbox, you can
use the SS command; or use SSDATA.

sys = ss(model('measure')) %if you only want the measured component of
model (ignore noise component, such that y = B/Au is converted)
