Identifying Input-Output Polynomial Models
1 In the System Identification Tool GUI, select Estimate > Linear
parametric models to open the Linear Parametric Models dialog box.
The ARX model is already selected by default in the Structure list.
Note For time-series models, select the AR model structure.
2 Edit the Orders field to specify a range of poles, zeros, and d elays. For
example, enter the following values for na, nb,andnk:
[1:10 1:10 1:10]
Tip As a shortcut for entering 1:10 for each required model order, click
Order Selection.
