Hello,
I went and tried to do a simple rlocus this evening, but it wasn't simple.
I'll put a transcipt at the end of the page, how do I make this work?

rlocus is the user-defined function from the file
/opt/octave/share/octave/2.1.35/m/control/base/rlocus.m
- Function File: rlocus (INPUTS)
[rldata, k] = rlocus(sys[,increment,min_k,max_k])
Displays root locus plot of the specified SISO system.
----- --- --------
--->| + |---|k|---->| SISO |----------->
----- --- -------- |
- ^ |
|_____________________________|
inputs: sys = system data structure
min_k, max_k,increment: minimum, maximum values of k and
the increment used in computing gain values
Outputs: plots the root locus to the screen.
rldata: Data points plotted column 1: real values, column 2: imaginary
values)
k: gains for real axis break points.
