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

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,..

Java-based standard calculator with GUI or command-line interface.

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 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.

A cross-platform, text-interpreting calculator written in the Java programming language. Runs on any computer with Java 6 or higher installed. Functions much like a Ti-84, but without the graphing utility.

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.

The Java Data Mining Package (JDMP) is a library that provides methods for analyzing data with the help of machine learning algorithms (e.g. clustering, classification, graphical models, neural networks, Bayesian networks, text processing, optimization).

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.

JECL, pronounced "Jekyll", is an open-source Java library implementing a variety of evolutionary algorithms. The goal is to provide a uniform interface for describing problems, running evolutionary algorithms, and accumulating results. The Java Evolutionary Computation Library is no longer under active development. We suggest the MOEA Framework (http://www.moeaframework.org/), jMetal (http://jmetal.sourceforge.net/), ECJ (http://cs.gmu.edu/~eclab/projects/ecj/) or JGAP (http://jgap.sourceforge.net/) as alternatives.

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 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).

Computes and displays Lindenmayer Systems. The programming language is Java.

JLAL is a linear algebra package for java, providing an easy to use object-oriented API. The library supports arithmetic operations, inversion, various matrix decompositions, solution of linear equations, and more.

Java Math Library (JML) is a fairly robust mathematics library that can be used for anything from basic calculations to some more advanced mathematical functions.
