Root Locus

(OP)
Hello,

My problem is about using the function "rlocus" existing in Matlab.

As far as I know, "rlocus" is designed to plot all the possible pole locations as the value of the "feedback gain" in a block diagram changes from "0" to "inf".
What I cannot do is to observe all the possible pole locations of the closed loop system as one of my "plant parameters" change. What should I do?

Thank you
Erdem
