Rlocus plot- Xlimit and Gain for stability limit

[swagata Mukherjee]

Dear All,

Hope you are keeping well.

I need to know the following:

i. In Octave Root Locus plot is it possible to add Xlimit and ylimit to plot only the area of interest?

ii. Is it possible to get the gain for stability limit?

Regards,

Swagata
