Details:

grpdelay fails if the coefficient vectors are columns. 

This script:

version
warning ("error", "Octave:broadcast");
DR=[1.00000 -0.00000 -3.37219 0.00000 ...
    5.45710 -0.00000 -5.24394 0.00000 ...
    3.12049 -0.00000 -1.08770 0.00000 0.17404];
N=[-0.0139469 -0.0222376 0.0178631 0.0451737 ...
    0.0013962 -0.0259712 0.0016338 0.0165189 ...
    0.0115098  0.0095051 0.0043874];
[T,w]=grpdelay(N,DR,1024);
plot(w/pi,T)
T=[];
warning ("off", "Octave:broadcast");
[T,w]=grpdelay(N',DR',1024);
plot(w/pi,T)


produces:
