Follow-up Comment #2, bug #44930 (project octave):
No, I'm afraid I don't have Matlab. Using a default denominator of 1 is fine;
roots([1]) returns []. My criticism is that zplane pads the zero or pole
column vectors with 0, implying poles or zeros at z=0 that are not in the
input polynomial.
This is not a Matlab compatibility bug. It is an incorrect result.
