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.

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.

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.

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/)

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.

MIDP or some KVM implementation don't support float or double type. There is a Java Math Library implement the most math functions in a Parametric Math Fixed Point Package. This package use only integer type.

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.

A full math Java class library containing complex functions and algorithms such as cubic-spline interpolation, least squares, matrix computations. Eventually to make a web based interface to the library using JSP.

This is a collection of Java Applications, Libraries and Apletts. Also some mathematial applications are contained.

A thoughtfully designed Java library for dealing with Matrices ( Matrix Theory ). Simple, Intuitive and Flexible. The library revolves around a Matrix interface. Operations are thoughtfully distributed. Not guilty of exposing all-in-one Matrix class.

Java Micro Benchmark - control tasks required to determine the comparative performance characteristics of the computer system on different platforms. Can be used to determine the effect of different software on the performance of a computer system.

This is a Java library for manipulating Oriented Matroids.
