Follow-up Comment #10, bug #55968 (project octave):
@Z.M. It depends what you mean by "work". In your original example, the result
of rewrite will be a symbolic variable. If you 'disp' that variable, it will
print itself as if it were "sinc(w/10)"
⎛ω ⎞
sinc⎜──⎟
⎝10⎠
You will have to ignore the way that it looks, because Python is generating
that appearance.
But if you evaluate that function, or turn it into an inline Octave function,
it will evaluate to the right thing in terms of Octave's normalized sinc
function.
>> double (subs (fn, 10))
ans = 0.84147
>> f = matlabFunction (fn)
f =
@(omega) sinc (omega / (10 * pi))
>> f(10)
ans = 0.84147
