Math::Polynomial::Solve, version 2.00, 10 Feb 2004. ---------------------------------------------------------------- Copyright (c) 2004 John M. Gamble. All rights reserved. This program is free software; you can redistribute it and/or modify it under the same terms as Perl itself. This package provides a set of functions that find the roots of polynomials up to degree 4 using the classical methods. Polynomials of degrees 5 and higher are 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 . 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, . 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-2.00.tar.gz tar xvf Math-Polynomial-Solve-2.00.tar Go into the resulting directory, and type: perl Makefile.PL make Run the tests: make test Install the module: make install
