Octave Gurus,

I am trying to change the step size and range of the "gain" of my system while using rlocus and cannot seem to get it to function properly.

I have the following packages installed (control and signal), and am using qtoctave as a GUI front-end.

According to your documentation, I should be able to change the step size following the syntax:

rlocus(sys, [step,min,max]);

Yet, I am getting errors. Is this possible another way, utilizing a k-vector and multiplying into the system transfer function prior to using rlocus? Or am I using this wrong (very likely :])?

Any help you can give me would be great!

Thanks.

try

rlocus(sys, step,min,max);
