The following figure shows a sample nonlinear ARX plot.
Configuring the Nonlinear ARX Plot
To include or exclude a model on the plot, click the corresponding model icon
in the System Identification Tool G U I. Active models display a thick line
inside the Model Board icon.
To configure the p lo t:
1 If your model contains multiple output, select the output channel in the
