Follow-up Comment #1:

I see fails occuring with the run of the test data:

octave:4> a = [1 0.5]; b = [3 1];
octave:5> isminphase (b, a)
error: Invalid call to isminphase.  Correct usage is:

 -- Function File: L = isminphase (B, A)
 -- Function File: L = isminphase (SOS)
 -- Function File: L = isminphase (..., TOL)





octave:3> [b, a] = butter (1, .5);
octave:4> a
a =

   1.0000e+00  -5.5511e-17

octave:5> b
b =

   0.5000   0.5000

octave:6> f = isminphase (b, a)
error: Invalid call to isminphase.  Correct usage is:

 -- Function File: L = isminphase (B, A)
 -- Function File: L = isminphase (SOS)
 -- Function File: L = isminphase (..., TOL)
