Symja is a computer algebra system and symbolic mathematics library written in Java.
It’s designed for symbolic and numerical work, giving users tools for manipulating expressions, performing calculus and algebra operations, solving equations, and building mathematical functionality into Java applications. The project also provides interactive interfaces including REPLs, notebook-style components, and web-based access to the Symja language.
This is free and open source software.
Key Features
- Supports arbitrary precision integers, rational numbers, complex numbers, polynomial functions, lists and associations.
- Provides symbolic differentiation, integration, equation solving, linear algebra, number theory, combinatorics, logic and polynomial functions.
- Includes a general purpose term rewriting system and pattern matching engine for symbolic manipulation.
- Lets developers work with human-readable mathematical expressions or the internal abstract syntax tree representation in Java.
- Offers console and Mathematica-like REPLs, servlet-based notebook interfaces, and a JSON web API server.
- Uses Rubi-based symbolic integration rules and can compile numeric functions with the Janino Java compiler.
- Integrates with open source libraries such as Hipparchus, Tablesaw, JGraphT, LogicNG, JAS and apfloat.
