[Octave-bug-tracker] [bug #61061] [octave forge] (control) margin() and step() giving wrong results

[HWe]

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 ?
