Hi Bram,
you have to use 'rlocus' function with the transfer function as input then a window opens up showing the root locus plot.
You can click on any of the point on the root locus to see the properties at that point.
I am attaching a screenshot and also the code I used to achieve the same. It was working as intended.
num=[1 2];
den=[ 1 2 1];
t=tf(num,den) ;
rlocus(t);
Please do check the procedure and make sure you are clicking on the curve only and not elsewhere.
Thank you,
Aditya.
