| 1 | Dear User:
|
|---|
| 2 |
|
|---|
| 3 | This archive contains files which provide Grobner basis support for
|
|---|
| 4 | the free computer algebra system Maxima. The older versions of the
|
|---|
| 5 | package are distributed with Maxima in the subfolder of the Maxima
|
|---|
| 6 | installation tree, like:
|
|---|
| 7 |
|
|---|
| 8 | maxima/5.xx.x/share/contrib/Grobner
|
|---|
| 9 |
|
|---|
| 10 | This version is meant to be a backward-compatible replacement for this
|
|---|
| 11 | package.
|
|---|
| 12 |
|
|---|
| 13 |
|
|---|
| 14 | == INSTALLATION INSTRUCTIONS ==
|
|---|
| 15 |
|
|---|
| 16 | In order to use the package,
|
|---|
| 17 | 1. Copy the files in this directory to your favorite location;
|
|---|
| 18 | or better, checkout the contents of this repository with SVN.
|
|---|
| 19 | 2. Edit the file "grobner.mac" to modify the location of the Lisp
|
|---|
| 20 | files, to reflect your choice made in previous step.
|
|---|
| 21 | 3. Start your Maxima and load the file "grobner.mac"
|
|---|
| 22 | 4. Optionally, compile the Lisp files, so that the next file
|
|---|
| 23 | you load "grobner.mac", the compiled (.fasl) versions of
|
|---|
| 24 | the files will be loaded. The compilation instructions
|
|---|
| 25 | vary slightly depending on Lisp version.
|
|---|
| 26 |
|
|---|
| 27 | This version has been verified to work under this Maxima version:
|
|---|
| 28 |
|
|---|
| 29 | ----------------------------------------------------------------
|
|---|
| 30 | Maxima 5.34.1 http://maxima.sourceforge.net
|
|---|
| 31 | using Lisp SBCL 1.2.4-1.fc21
|
|---|
| 32 | ----------------------------------------------------------------
|
|---|
| 33 |
|
|---|
| 34 | It should also be portable across other ANSI Common Lisp implementations.
|
|---|
| 35 |
|
|---|
| 36 | The file grobner.demo is a Macsyma-style demo file for most of the operations
|
|---|
| 37 | provided by the package. In order to run it, go to the Maxima level and
|
|---|
| 38 | type:
|
|---|
| 39 |
|
|---|
| 40 | demo("grobner.demo");
|
|---|
| 41 |
|
|---|
| 42 | or
|
|---|
| 43 |
|
|---|
| 44 | batch("grobner.demo");
|
|---|
| 45 |
|
|---|
| 46 | and watch the demonstration.
|
|---|
| 47 |
|
|---|
| 48 | Maxima documentation for this package has not been written yet, but
|
|---|
| 49 | there is a sizable amount of documentation in the LISP source.
|
|---|

|
|---|
| 51 | == COMPILATION INSTRUCTIONS FOR SBCL ==
|
|---|
| 52 |
|
|---|
| 53 | === When using ASDF (preferred way):
|
|---|
| 54 | ----------------------------------------------------------------
|
|---|
| 55 | > (require :asdf)
|
|---|
| 56 | > (load "ngrobner.asd")
|
|---|
| 57 | > (asdf:install-system :ngrobner)
|
|---|
| 58 | ----------------------------------------------------------------
|
|---|
| 59 | The compiled files (extension .fasl for SBCL) will be typically
|
|---|
| 60 | placed in a standard location determined by the ASDF configuration. On my system it is:
|
|---|
| 61 | ----------------------------------------------------------------
|
|---|
| 62 | /home/marek/.cache/common-lisp/sbcl-1.2.4-1.fc21-linux-x64/home/marek/Repos/MaximaGrobner/branches/f4grobner/
|
|---|
| 63 | ----------------------------------------------------------------
|
|---|
| 64 | given that the SVN repository was copied to /home/marek/Repos/MaximaGrobner.
|
|---|
| 65 |
|
|---|
| 66 | === When not using ASDF (for whatever reason):
|
|---|
| 67 |
|
|---|
| 68 | Step 1. Start SBCL in the directory which is a copy of this directory.
|
|---|
| 69 | Step 2. Execute Lisp commands:
|
|---|
| 70 | ----------------------------------------------------------------
|
|---|
| 71 | > (load "ngrobner-package.lisp")
|
|---|
| 72 | > (ngrobner::compile-ngrobner)
|
|---|
| 73 | ----------------------------------------------------------------
|
|---|
| 74 |
|
|---|
| 75 | The resulting compiled files (extension .fasl for SBCL) will end up in
|
|---|
| 76 | the same folder as the Lisp files. Then can be moved any directory
|
|---|
| 77 | where Maxima can find them, as determined by the variable
|
|---|
| 78 | file_search_lisp. This variable needs to be modified in "grobner.mac"
|
|---|
| 79 | accordingly. After that, every time you load "grobner.mac" the
|
|---|
| 80 | compiled version will be used.
|
|---|
| 81 |
|
|---|
| 82 | == ADDITIONAL COMMENTS ==
|
|---|
| 83 |
|
|---|
| 84 | The files were derived the sources of a package CGBlisp, version 2,
|
|---|
| 85 | also authored by me, which will eventually be released at my Web site
|
|---|
| 86 | (see below). An older version of CGBlisp is available at the Web
|
|---|
| 87 | site.
|
|---|
| 88 |
|
|---|
| 89 | Enjoy.
