quartic polynomial solver

[Lothar Leidner]

Hi,

I'm looking for a java method or Math lib which solves quartic
polynomial equations a4 x^4 + a3 x^3 + a2 x^2 + a1 x + a0 = 0.
My google results pointed to dead links. Any help appreciated.

Thanks,

Lothar Leidner

If you have the time (and don't find what you want), you could download the
pov-ray (www.povray.org) source (written in C) and translate their quartic
solver to java.
Should be rather straightforward.

Another approach is to get a textbook such as Anthony Ralston's First
Course In Numerical Analysis.
