Symja Library - Java Symbolic Math System

Note: this repository contains the Java 8 version of the project.

Quick start

Read the Symja Manual for the description of the Symja language.

Features of the Symja language:

  • arbitrary precision integers, rational and complex numbers
  • differentiation, integration, equation solving, polynomial and linear algebra functions...
  • a general purpose Term Rewriting System and Pattern Matching engine
  • use human readable math expression strings or the internal abstract syntax tree (AST) representation to code in Java. See the Unit test examples



Console Examples

>>> 24/60

>>> N(24/60)

>>> sin(30*degree)

>>> sin(pi/2)

>>> a+a+4*b^2+3*b^2

>>> solve({x^2-11==y, x+y==-9}, {x,y})

>>> dsolve({y'(x)==y(x)+2,y(0)==1},y(x), x)

>>> integrate(cos(x)^5, x)

>>> D(sin(x^3), x)

>>> factor(-1+x^16)

>>> factor(5+x^12, Modulus->7)

>>> expand((-1+x)*(1+x)*(1+x^2)*(1+x^4)*(1+x^8))

>>> det({{1,2},{3,4}})

>>> inverse({{1,2},{3,4}})

>>> factorinteger(2^15-5)

>>> refine(abs(n*abs(m)), n<0)

Maven Usage

Using Maven, add the following to your pom.xml



and run

mvn clean install

With the following command you can run the Symja console from the command line

mvn exec:java -pl matheclipse-core

With the following command you can run a symja console with a Mathematica-compatible syntax and functions

mvn exec:java@mma -pl matheclipse-core 

With the following command you can build a fat jar which contains all needed classes

mvn assembly:single -pl matheclipse-core

The Excelsior JET Maven Plugin provides Maven users with an easy way to compile their applications down to optimized native Windows, OS X, or Linux executables with Excelsior JET.

mvn jet:build -pl matheclipse-core

Getting started

First, you'll need a Java Development Kit compatible with Java 8 or later.

You can find JDK installers at:

If you're unsure how to install the JDK, you can find instructions for all operating systems here:

Pay careful attention to anything about setting up your PATH or CLASSPATH.

Install and open the latest version of the Eclipse development IDE:

BitBucket GIT

a) Fork the Symja repository to use as a starting point.

  • Navigate to in your browser.
  • Click the "Fork" button in the top-right of the page.
  • Once your fork is ready, open the new repository's "Settings" by clicking the link in the menu bar on the left.
  • Change the repository name to the name of your Library and save your changes.

b) Clone your new repository to your Eclipse workspace.

  • Open Eclipse and select the File → Import... menu item.
  • Select Git → Projects from Git, and click "Next >".
  • Select "URI" and click "Next >".
  • Enter your repository's clone URL in the "URI" field. The remaining fields in the "Location" and "Connection" groups will get automatically filled in.
  • Enter your BitBucket credentials in the "Authentication" group, and click "Next >".
  • Select the master branch on the next screen, and click "Next >".
  • The default settings on the "Local Configuration" screen should work fine, click "Next >".
  • Make sure "Import existing projects" is selected, and click "Next >".
  • Eclipse should find and select the symja_android_library automatically, click "Finish".
