Follow-up Comment #4, bug #47900 (project octave):

Looks like I also need this feature.

I'm trying to design an second order Sallen-Key bandpass filter from
this post], slightly modified version:

s = j*w;
B=[G*R*C*w*s 0 ];
A=[(R^2)*(C^2)*(w^2)*(s^2) R*C*w*(3-G)*s 1];

When trying to run this script:

   error: tf: numerator 'num' must be a real-valued, non-empty vector or a
cell of such vectors

I would be very appreciated for any info related to status of implementing of
this functionality. Thanks!
