Follow-up Comment #4, bug #61061 (project octave): Thanks for confirmation of the bug. Leaving out the zeros for the s^1 and s^2 coefficients will be difficult, because the TF is generated automatically. The bode(ax_0) phase is plotted from 360deg on and not from 0deg as expected. Interestingly the margin(ax_0) phase is plotted correctly and the phase margin is calculated correct. How can I apply your workaround of ignoring the stable poles of higher than 20 times the dominant pole ? Is there any function or workaraund to do that ? _______________________________________________________ Reply to this item at: <https://savannah.gnu.org/bugs/?61061> _______________________________________________ Message sent via Savannah https://savannah.gnu.org/
