JQHull is a Brad Barber's QHull library (http://www.qhull.org) wrapped in Java.

JQuantity is a set of Java classes which enable developers to build scientific applications using quantities which are either exact or have known (bounded) errors. Quantities may include units, may be complex, non-scalar, etc. Extends java.math classes

JResolution is a simple, flexible, easily-maintained Java program for resolution-theorem proving which allows re-configurations for the various restrictions of the resolution-rule as determined by an (expert) user.

JStats is a small but powerful Java application/applet for conducting statistical tests. The following tests are supported: * Parametric tests: T-test, ANOVA, Repeated Measures ANOVA * Non-parametric tests: Wilcoxon Rank-Sum, Wilcoxon Signed-Ranks, Kruskal-Wallis, Friedman * Check if datasets are normally distributed: Jarque-Bera, Shapiro-Wilk * Check if datasets have equal variances: F-test, Bartlett's test, John, Nagao and Sugiura's test * Correlation: Correlation coefficient, Spearman Rank correlation, linear regression * Confidence intervals test * Outliers: Generalized Extreme Studentized (ESD) test, outliers in ANOVA The latest version is available as applet on http://aiguy.org/Statistics.html

Java-based extensible high-precision math package. Includes support for computations based on fractions. Support is included for converting to floating point numbers and BigDecimals.

JVClifford is composed of Java/Java3D packages and executables jars that provide for Clifford element definition, Geometric Algebra operations and geometric scenes modelling and rendering using the n-dimensional geometric algebra affine model

JVisual3D is a GUI library, 3D geometry viewer and a mathematical visualization software written in pure java. It is comparable with the well known javaview project. This is under GPL. Create, manipulate and display easiely meshes, 3d shapes, surfaces,..

Jafama (Java Fast Math) consists of fast - but not sloppy - counterparts of java.lang.Math treatments, plus additional ones. They are usually about 2-4 (up to 15) times faster, with about 1e-15 accuracy, and handle special cases (NaN, etc.). Since version 2.1, a StrictFastMath class is also provided. It is a strictfp version of FastMath (and not a fast version of StrictMath): for a same version of this library, its methods always return a same result for same arguments, which might not be the case for FastMath depending on JIT or other JVM optimizations. Requires Java 5 or later. Available on Central since 2015/06/05. Also available on github since 2015/12/13: https://github.com/jeffhain/jafama

Jafaran (Java Fast Random) provides fast, and for some more random, implementations of java.util.Random, with additional nextXXX() methods, and methods to retrieve and restore state. The names of implementations contain "Conc" (for concurrent) if they are thread-safe and non-blocking, or "Seq" (for sequential) if they are not thread-safe. Also provides an implementation of Ziggurat algorithm (based on J. A. Doornik paper, 2005), used by nextGaussian() methods of the provided implementations. Requires Java 5 or later. Also available on github since 2015/12/13: https://github.com/jeffhain/jafaran Principal classes: - Implementations using Mersenne-Twister algorithm (good pseudo-randomness): MTSyncRNG MTSeqRNG - Implementations using Marsaglia Xor-Shift (fast): MXSIntSeqRNG (32 bits) MXSLongSeqRNG (64 bits) (nextLong() faster, larger period) - Ziggurat: Random-based implementation of Ziggurat algorithm.

Port of the Jasymca Symbolic Calculator for Mobile Devices to the Android Platform

The JAccumulator package brings the convenient type conversion and ad hoc composition capabilities of Javascript to Java programming structures. JAccumulator is dependent upon the Jupperware (http://jupperware.sf.net) to provide Javascript-like associative list capabilities and the convenience of easy hierarchical construction.

The Java Astrodynamics Toolkit is a library of components to help users create their own application programs to solve problems in astrodynamics, mission design, spacecraft navigation, guidance and control using Java or Matlab.

Generates the Reverse Polish Notation (Postfix) expression form of an arithmetic expression in (Infix) form. Performs the computation of the arithmetic expression if Integers or Floating point numbers are used in the expression. Supports PEDMAS order of computation, thus, all the operators of Exponentiation, Division, Multiplication, Addition and Subtraction, as well as using Parentheses for grouping and prioritization is all handled.

Java Calculator Suite (jcs) is a collection of Java classes related to expression calculators written in Java. Suports booleans, large numbers, machine numbers, most operators and about 25 different functions.

This project will be a project that will be used by Speleologist (cavers) to help aid in the mapping of the underground world. It will be simple at first.. only allowing the entry of survey (dist/azmith/V-angle) and give back a line plot..

Java Complex is a complex number library for Java.

This project has been moved to bitbucket.org: - https://bitbucket.org/vahidi/jbdd/wiki/Home - https://bitbucket.org/vahidi/jdd/wiki/Home It includes two libraries for working with decision diagrams: - JBDD: a Java interface to two popular BDD libraries, CUDD and BuDDy - JDD: a native Java library supporting BDD, Z-BDD

A library written in Java for performing calculations in the Dempster-Shafer theory of evidence.

JFEP is a Java fast mathematical expression parser and evaluator. It is designed to avoid inefficiency and to support multiple evaluations without overhead.

JFD is an educational Java tool for computing the formal derivative of an expression. It recognizes the regular operators, parentheses and functions. It can also be extended with custom functions and/or operators.

Java ILP is a simple java interface to (mixed) integer linear programming solvers such as lp_solve, Glpk, Gurobi, SAT4J (0-1 ILP), MiniSat+(0-1 ILP), CPLEX, or Mosek. (documentation at http://javailp.sourceforge.net/)

Java Kohonen Neural Network Library Kohonen neural network library is a set of classes and functions for design, train and use Kohonen network (self organizing map).
