Follow-up Comment #4, bug #45334 (project octave):
I had a quick look at the problem and noticed the following:
- the transfer function matrix from Maxima is the transpose of the one from
Matlab/Octave. (you can use a1.' in Octave, note the dot)
- the tolerance on line 120 of the file @tf/__sys2ss__.m has a huge impact on
the results.
