Math::Polynomial::Solve, version 2.10, 3 Apr 2006.

This package provides a set of functions that find the roots of
polynomials up to degree 4 using the classical methods. These polynomials
and polynomials of degrees 5 and higher may also be solved by an
implementation of the QR Hessenberg algorithm.

The solution for the cubic is based on an article by R. W. D. Nickalls,
"A New Approach to solving the cubic: Cardan's solution revealed," The
Mathematical Gazette, 77, 354-359, 1993. This article is available on
the web at several web sites, including
<http://www.2dcurves.com/cubic/cubic.html> and my own web site
<http://pages.ripco.net/~jgamble/docs/nickallscubic.pdf>.
A web search for Nickalls + cubic will find other web sites.

The solution for the quartic is based on Ferrari's method, as described
in the web page Karl's Calculus Tutor,
<http://www.karlscalculus.org/quartic.html>.

Version 1.01 of this package worked with perl version 5.004_04. The
current version may work with that version of perl as well, but I had
no way to test this. Consequently, the requirement is set for version
5.6 of perl.

Installation:
----------------------------------------------------------------
The usual way.  Unpack the archive:
	gzip -d Math-Polynomial-Solve-2.10.tar.gz
	tar xvf Math-Polynomial-Solve-2.10.tar

This package now makes use of Module::Build, and the Build.PL script,
but you can still use Makefile.PL, which is provided:

Go into the resulting directory, and type:
	perl Makefile.PL
	make

Run the tests:
	make test

Install the module:
	make install

Alternatively:
	perl Build.PL
	Build

Run the tests:
	Build test

Install the module:
	Build install

See the documentation for Module::Build for more information.
