[Octave-bug-tracker] [bug #55031] lsode doesn't integrate correctly if the right side of the equation is not continuous in t

Follow-up Comment #5, bug #55031 (project octave):

I've uploaded simplified version of file, where the bug is triggered.

[u_ref u_ref/R] with u_ref/R=0.8 is a stable point. Therefor when the control
u oscillates rapidly, there have to be no movements from constant away.

With freq=1e-6 and time-stepping 1000 there are no problems.
But with freq=1e7 and time stepping 10000 -- yes, there are.
