JAS: Java Algebra System
========================

Version 2.5, January 2013

by Heinz Kredel, University of Mannheim, kredel at rz.uni-mannheim.de

Copyright (c) 2005-2013 by Heinz Kredel.

Programms released under GPL or LGPL, see COPYING.jas or COPYING.lgpl.jas.

Web home-page: http://krum.rz.uni-mannheim.de/jas/


Requirements
------------

A Java JDK 1.6 or JDK 1.7.

Documentation see index.html.

Required libraries are log4j.jar (from Apache Log4j, or mylog.jar, droidlog.jar) 
and junit.jar (from Junit for tests in trc) 


Usage
-----

javac -cp {other_jar_files}:jas-<version>-bin.jar:.  <your sample code>

java  -cp {other_jar_files}:jas-<version>-bin.jar:.  <your sample class>

or

jython examples/<some input file> 

or

jruby examples/<some input file> 


Versions and jar files
----------------------

JAS is distributed in 3 jar files:

jas-<version>-bin.jar:    the Java class files 
jas-<version>-src.zip:    the java source code
jas-<version>-doc.zip:    the Java doc, epydoc, jrdoc and more info files

optional jar files:

jas-meditor.jar:          the interface to meditor
jas-jython.jar:           an interface for Java scripting
jas-mpj.jar:              MPI Java depending code
mylog.jar:                a substitute for log4j to use Java logging
droidlog.jar:             a substitute for log4j to use Android logging
jlinalg_adapter.jar:      an adaptor to parts of JLinAlg
commons-math_adapter.jar: an adaptor to parts of Apache commons.math

There is a GIT repository for the scource code, which can be cloned with

  git clone http://krum.rz.uni-mannheim.de/jas.git  jas


The version is specified by a two digit major.minor number
and a subversion revision number. For example in

jas-2.2.2088-bin.jar

"2.2"  is the JAS version number and
"2088" is the subversion revision number

The jas-*-bin.jar and jas-*-doc.jar can be generated from jas-*-src.jar.
The fastest way to get a complete JAS install, is 

> jar -xf jas-<version>-src.zip
> cd <JAS version number>
> jar -xf jas-<version>-bin.jar
> jar -xf jas-<version>-doc.zip

If you have a working ant, the last two steps can be replaced by

> ant compile
> ant doc

provided you have setup build.xml and the required libraries.


Directory structure
-------------------

.          main directory, with html documentation
+doc       javadocs, jython docs, jruby docs
+edu       Java class files
+examples  examples for jython, jruby and jas
+images    images for html docs
