Details:
I have found a discrepancy between the matlab specification and
the octave implementation of the zplane function, found in the signal
package.
The octave implementation does not give any output values, but matlab does:
[hz,hp,ht] = zplane(___) returns vectors of handles to the zero lines, hz, and
the pole lines, hp. ht is a vector of handles to the axes/unit circle line and
to text objects, which are present when there are multiple zeros or poles./

When I try to do e.g.
[hz,hp,ht] = zplane([0; 1; 1i], [0.3; 0.1])
The error
error: element number 1 undefined in return list
is printed. This should be a valid expression.
