Subject: Factoring High Order Polynomials
Does anybody know where the description is published of the algorithm
Matlab uses to factor polynomials of arbitrary order? Since it
doesn't require the user to input an initial guess, it can't be a
numerical method, leaving only the method based on theta functions
(ie. elliptic integrals).
If that's the case, it means that the bugs have all been worked out of
the theta function method. If so, does anybody know where I could
find the paper that presents that solution in detail? I've already
read King's book "Beyond the Quartic," and although it is very
edifying, the equation for the polynomial roots is not covered in
nearly enough detail for someone to write the algorithm.
