Closing as a duplicate of bug #49318.

Yes, this is more than cosmetic, since certain Matlab functions are written to take either zeros/poles or numerator/denominator vectors, and the only difference is the orientation of the vectors.

a rather minor point discovered while looking into other issues with the cheby2 output, but in Matlab 2016b the output for the three parameter outputs from cheby2 are a column vectors, not row vectors. see below:

Octave 4.2.0 with signal package 1.3.2 produces a row vector for both 2 and 3 output forms (col vector shown for easier display):

Matlab 2016b output:

while many functions in the signal package seem to be fine with either a row or column vector, it would seem there may be cases where code compatibility is impacted by the difference.
