[Octave-bug-tracker] [bug #53897] poly of conjugate complex pairs should return a real polynomial

[Rik]

Follow-up Comment #5, bug #53897 (project octave):

That seems to work.  Would the call to eig ever return values which are not
exactly complex conjugates such that we need to use a tolerance on the
equality test?  In other words,


if (all (abs (sort (x(imag(x)>0)) - sort (conj (x(imag(x)<0)))) < tol))
