• ArciMath BigDecimal Fast and improved BigDecimal class. [Commercial/Free]
• JMatLink Connects Java and MATLAB. Native methods make it possible to use MATLAB's computational engine inside your own java applications, applets and servlets. [Freeware, source available]
• JeksParser Parses and computes expressions or functions primarily for use in spreadsheet applications such as the example provided. [Beta Evaluation]
• Java Numerics Working group that offers presentation, news, and libraries related to numerical computing.
• Math Parser Package to parse and evaluate mathematical expressions at runtime. [Commercial]
• Significant Figures Handles parsing, rounding, and displaying numbers for scientific applications.
• JEPLite A light-weighted (re)implementation of the Java Expression Parser (jep.sourceforge.net). The intention is to strip some of its not-so-often-used features, and thus speeding the rest. Includes expression optimizer. [Open source, GPL]
• JFormula A Java library for evaluating mathematical expression. It is compatible with the JDK 1.1 and later. [Shareware]
• Jep Java - Mathematical Expression Parser Java classes for parsing and evaluating mathematical expressions. Supports multiple variables and user-defined functions. [Open source, GPL or commercial]
• JMathTools A mathematical Java toolbox designed to be easily used and modified for scientific software engineering. [Open source, BSD License]
• Mantissa (Mathematical Algorithms for Numerical Tasks In Space System Applications) A class library devoted to simulation, including an ODE solving package, as well as least square estimators, solvers, polynomials, basic statistics features. [Open source, BSD-like]
• AutoAbacus An equation solving library that finds solutions to equation sets. A set of equations can be passed in as text, while AutoAbacus attempts to find a solution that satisfies all constraints. [Commercial, trial version]
• Implicit Graph Search Library Search algorithms on graphs implicitly given by tree node expansion operator and edge transition cost function. Site includes short description and download option. [GNU Library or LGPL]
• JMathLib Java clone of FreeMat, Matlab, Octave and Scilab. Site includes documentation, handbook, demos, and download option. [GPL, LGPL]
• SuanShu Java mathematical, numerical, and statistical library, providing classes representing many mathematical concepts. Site includes examples and a free trial download. The proprietary license looks quite "interesting".
• JGraphT A class library that provides mathematical graph-theory objects and algorithms. JGraphT supports a rich gallery of graphs and is designed to be powerful, extensible and easy to use. [Open source, LGPL]
