Put a Discrete-time ARX model into simulink

I use System Identification tool and get a Discrete-time ARX model. How can I put this model into simulink? Thank you!

The System Identification Toolbox has Simulink blocks in a "System Identification Toolbox" library. For linear ARX models, you can bring in an Idmodel block. In this block dialog, simply fill in the same of the model -- in your case, arxqs.

Note that you might want to either save the MATLAB code you used to generate this model, or save the model itself in a MAT-file, since you presumably want this variable to be loaded every time you open your Simulink model.
