Dear User: This archive contains files which provide Grobner basis support for the free computer algebra system Maxima. In order to use the package, 1. Copy the files in this directory to your favorite location; or better, checkout the contents of this repository with SVN. 2. Edit the file "grobner.mac" to modify the location of the Lisp files, to reflect your choice made in previous step. 3. Start your Maxima and load the file "grobner.mac" 4. Optionally, compile the Lisp files, so that the next file you load "grobner.mac", the compiled (.fasl) versions of the files will be loaded. The compilation instructions vary slightly depending on Lisp version. This version has been verified to work under this Maxima version: ---------------------------------------------------------------- Maxima 5.34.1 http://maxima.sourceforge.net using Lisp SBCL 1.2.4-1.fc21 ---------------------------------------------------------------- It should also be portable across other ANSI Common Lisp implementations. The file grobner.demo is a Macsyma-style demo file for most of the operations provided by the package. In order to run it, go to the Maxima level and type: demo("grobner.demo"); or batch("grobner.demo"); and watch the demonstration. Maxima documentation for this package has not been written yet, but there is a sizable amount of documentation in the LISP source. ====================================================== COMPILATION INSTRUCTIONS FOR SBCL ====================================================== When using ASDF: ---------------------------------------------------------------- > (require :asdf) > (load "ngrobner.asd") > (asdf:install-system :ngrobner) ---------------------------------------------------------------- ====================================================== The files were derived the sources of a package CGBlisp, version 2, also authored by me, which will eventually be released at my Web site (see below). An older version of CGBlisp is available at the Web site. Enjoy. --Marek Rychlik 5-24-2002 Revised: 1-25-2009 Revised: 1-25-2015 E-mail: rychlik@u.arizona.edu URL: http://marekrychlik.com
