Bug #43947 is essentially the same issue, both the num and den properties should have the same length for Matlab compatibility, as well as the vectors returned by tfdata.

Mike Miller <mtmiller>

Mon 07 Dec 2015 12:37:43 AM UTC, original submission:

The vectors containing the numerator and denominator coefficients have the same length in Matlab. Coefficients of terms that have exponents bigger than the degree of the other polynomial are given as 0. In Octave, they don't appear in the returned vector and thus NUM and DEN can have different lengths.

pkg load control
s=tf('s')
g=1/(1+s)
[num,den]=tfdata(g)
