[Octave-bug-tracker] [bug #45918] control: Nyquist plot is incorrect

[Lukas Reichlin]

Follow-up Comment #6, bug #45918 (project octave):

This


nyquist (sys, {2e-1, 1e2})


shows you the same portion of the Nyquist plot as on this page


http://www.wolframalpha.com/input/?i=transfer+function+10*%281-s%29%2F%28%28s%2B1%29*s%29&dataset=


However, you need to apply this patch


https://bitbucket.org/paramaniac/control/commits/b23c696a02f0454f3582570b74a29f5d7b18f32e


before you can specify a frequency range for Nyquist plots. So thanks to your
bug report, I squashed a bug which was unrelated to the original problem ;-)
