Invoke the function by calling with a transfer function as its argument.

>> mySys=tf([1 3],[1 5 12 8 0])
>> RLocusGui(mySys) %Invoke GUI

Thought Matlab can create root locus plots, it is still useful to sketch root locus plots by hand. The program, RLocsuGui, takes loop gain as input and then applies (and visually demonstrates) all of the rules that are typically used to sketch the plot by hand.

The program also creates a web page describing the rules as applied to the given loop gain.

The zip file contains a ".m" file and a ".fig" file. Put them both in a directory that is in the Matlab path.

excellent work ! Thank you !

Adam Din

Absolutely phenomenal code from yourself! Literally helping me pass control systems engineering, the code is so simple, you can just change the transfer function and it does the rest itself. 10/10 sir

at line 97 of the code you can change the tranfer function.

in this gui only upto 7 variables are possible and so 7 is the limit how to increase the limit?

Correction: It would be really nice if I didn't have to dig through the code to edit the function

Colin King

Really nice GUI. It would be really nice if we could input our own transfer function, however.

amazing work. made learning root locus became easier.
