Hi there,
does anyone know how to change the frequency unit in the plot generate by the viewGoal() function, e.g. for a tuning goal like TuningGoal.Tracking, without doing a right click and using the properties dialog? The default option is rad/second, but I'd like to have Hz as default. Is there a command I can use in my script calling the viewGoal() function to set the frequency unit automatically to Hz? Is seems there is not "plotoptions" like bodeplot has.
Best regards, Robert

Hi,
Try this:
gmax = frd([1 1 0.01],[0 1 100]);
Req = TuningGoal.MaxGain('du','u',gmax);
viewGoal(Req);
h=gcr;
setoptions(h,'FreqUnits','Hz');
Hope this helps.
