Open Source Java Mathematics Software

oj! Algorithms - ojAlgo - is Open Source Java code that has to do with mathematics, linear algebra and optimisation; particularly (but certainly not exclusively) suitable for the financial domain.

A fully customizable, extensible, scalable computational engine pluggable with various statistical and mathematical engines (R, Matlab, Octave, scilab...) The main focus and datatype considered is timeseries: the project contains also a portable and effi

This is meant to be a powerful, but easy to use math software. It's by the user and for the users.

Don't hard-code data-structures for Artificial Intelligence (AI). Evolve them (and control flow) as cycles of arrays in arrays with size constraints based on other array sizes (at specific index) in terms of range, multiply, exponent, or permutation. No working code yet. Whats there now is an extension of GigaLineCompile which would become part of Human AI Net, but there are other projects to finish before I can come back to this one.

Expression4J (Math Expression Parser) is a java framework used to manage mathematic expression stored in String object like "f(x,b)=2*x-cos(b)" or "g(x,y)=f(y,x)*-2". Expression gramar can be define by user (add new operator or type ...)

In the tradition of Hilbert's program we create a formal correct (checkable by a proof verifier) but readable (like an ordinary LaTeX textbook) mathematical knowledge base which is freely accessible within the internet. Logic and set theory started.

A graph library, developed in Java.

Magic Fixed Point, it's an library that abstracts the use of fixed point math for environments that doesn't have floating point operations or in places that you don't want to use the traditional floating point operations.

Java library for simple managing and solving sophisticated mathematic expressions and equations, based on Reverse Polish Notation (RPN)

Numerikus is an attempt to build a set of numerical libraries written in C/C++, Fortran, Java and C# for single processor and multi-core processors. It wil have from basic functions to Linear Algebra solvers and ODE's and PDE's methods.

Una calculadora enfocada para programadores.

RunAsApproximator es un programa java multilenguaje que implementa algoritmos numéricos. Los datos de entrada son aquellos requeridos por cada algoritmo y los de salida son resultado final y los datos intermedios necesarios para alcanzar su resolución.

A shell for using the methods of Contextual Logic to do qualitative data analysis, mathematical research on the theory underlying Conceptual Knowledge Processing, or learning Formal Concept Analysis. It uses the framework provided by the Tockit project..

This project has moved. Please follow the WWW link below.

The Wolfram Machine project is an effort to create a set of documentation and useful modules (both hardware and software) for a computing architecture based on the mathematical theories presented in Steven Wolfram's book _A_New_Kind_of_Science_.

VectTens is an object-oriented numerical library designed to manipulate vectors, tensors, and other mathematical quantities in a simple and efficient manner.

jMathematics is a Java based mathematics framework and library. It solves numerical and symbolic calculations. It is designed to be integrated in a wide range of other applications.

Java OpenCL Process Virtual Machine. Spring IoC based framework for complex data analysis with OpenCL computing.

neuralnetgen is intended to be a universal neural net generator that receives a neural net description (on Neural Net Description Language, also developed on this project) and generates ANSI C code of a library that implements it.
