[Octave-bug-tracker] [bug #56560] Error by addition of two frd objects (control package)

[Jonas Frischknecht]

Follow-up Comment #2, bug #56560 (project octave):

It's just a simplified example to make clear where the error occurs. What I
want to do is to calculate a closed loop with a measured Plant P a discrete
controller C, like P*C/(1+P*C) and plot the bode diagramm. First I struggled
with (1+P*C) so I tried to generate an frd object for 1 (works in Matlab
directly). It didn't work so i tried to make an addition with two identical
systems.
