Follow-up Comment #12, bug#61355 (group octave):

While testing the patch I came across the issue that the phase correction
might not work when the user specifies an omega range that starts at high
frequencies where the phase might be already far away from the initial phase.
This effect also affects bode plots without poles or zeros at the origin: the
phase for an omega range at high frequencies might be wring since the
"history" of the phase starting at low frequencies is missing.

I have attached a version of bode.m which should fix this (including Juan's
fix for zeros or poles at the origin). Some tests and feedback are very much

(file #55459)
