Math::Polynomial::Solve, version 3.00, 19 Apr 2010. ---------------------------------------------------------------- Copyright (c) 2010 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, and a function for solving polynomials of any degree with an implementation by an implementation of the QR Hessenberg algorithm. The cubic is solved by the method described by R. W. D. Nickalls, "A New Approach to solving the cubic: Cardan's solution revealed," The Mathematical Gazette, 77, 354-359, 1993. Dr. Nickalls has made his paper available at . 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-2.50.tar.gz tar xvf Math-Polynomial-Solve-2.50.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, you can use Build.PL: perl Build.PL perl Build Run the tests: perl Build test Install the module: perl Build install See the documentation for Module::Build for more information.
