This is a project meant to provide users a series of tools to perform various mathematical actions

A java based programm which calculates a unitmatrix and their inverse-matirx from a given NxN-matrix

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 Metaheuristics (JMH) is a Java library aimed at the design and implementation of exact and approximated algorithms for optimization problems. JMH is specifically tailored for the design of metaheuristic procedures.

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 project aims to deliver a high-quality number base converter utility in Java. It will support decimal, binary, hexadecimal, octal, and a user specified base and convert between numbers of any base from 2 through 36.

This is a Java library for manipulating Oriented Matroids.

JRVFSim (Jarvis) is a simulator of a fluid dynamics phenomenon known as radial viscous fingering. Its main feature consists of taking jordan curves and simulating their evolution subject to various parameters. Includes a partial API for numerical methods

Raytracing rendering engine written in Java. Plug it into a modeling environment, or programmatically create a scene. Uses Constructive Solid Geometries (CSG), bounding boxes, and fully extensible design (at least eventually).

A java command-line application where the main goal is to solve any simplex problem. It's a team-work school project. It can be usefull for other students who needs to understand the simplex algorithm.

A set of components for doing text mining in Java. The target audience are other text mining developers who can use or extend these components.

JTSA is an educational time series analysis tool for simple calculations and forecasts using the additional or multiplicative seasonal decomposition method.

Multipresicion calculator, based on Bigdecimal Java class . It has a library (BigMath) that makes calculations with Bigdecimal. It has also an expression parser to parse the user input. It allows you to store user defined variables and functions . You can operate with them to be used for calculations or for creating new functions with composition. With the new version, you can also calculate the derivative of a function. JDK-17 compatibility You can find more about it at this web site: https://www.frojasg1.com:8443/downloads_web/web/html/calculadora.html?origin=sourceforge

JavaANPR is an automatic number plate recognition software, which implements algorithmic and mathematical principles from field of artificial intelligence, machine vision and neural networks.

A graph library, developed in Java.

Logo command and construct library for Java. Intended as a tool for teaching novice programmers the Java language and object orientation.

Javafastcomplex is a fast complex number package for Java. Most existing complex number packages implement only immutable complex numbers, which is easy to understand given that immutable objects lead to more understandable code. Mutable complex numbers would avoid garbage-collection penalty and therefore be faster in calculations. Javafastcomplex implements both mutable and immutable complex numbers, and has a common interface for both, allowing users to write functions that can take either a mutable or an immutable complex number as an argument. Mutable complex numbers can then be used in the most performance-critical parts of the code with immutable complex numbers being used elsewhere. Performance improvement of mutable complex numbers is 10x in the best-case scenario and about 2x in real life complex number code. The package is released under the liberal MIT license.

Jep is a Java package for parsing and evaluating mathematical expressions. It currently supports user defined variables, constants, and functions. The open-source Jep project was halted in favor of commercial development of version 3.0 upwards.

This project provides an interface to Java expression evaluator software. It does not itself provide expression capabilities but instead provides a common interface.

An online judge system to judge the ACM-ICPC programming contests.

The goal of this fractal renderer is to enable intricate images to be created with maximum control over the results. To this end, it supports multiple layers, many fractal types (including user – defined equations) and different ways of rendering.

D. R. Kaprekar found an interesting behaviour of four-digit number (say, 6349). Take any number; sort its digits in ascending (3469) and descinding (9643) order; subtract these (9643 - 3469 = 6174). Repeat these steps a couple of times. Surprisingly, you'
