Dynamic geometry program for use in schools and universities. Rich graphical interface, web export, graphics export, macros, assignments, animations and much more. Download the program via the links on the web page.

JGraphT is a free Java class library that provides mathematical graph-theory objects and algorithms. JGraphT supports a rich gallery of graphs and is designed to be powerful, extensible, and easy to use.

...GeoRegression provides the ability to estimate the closest point/distance between geometric primitives, best-fit shapes, and best fit geometric transform between sets of objects. It is designed for high performance and ease of use. GeoRegression has been release under an LGPL license for both commercial and non-commercial use.

jAgg is a Java 5.0 API that supports “group by” operations on Lists of Java objects: aggregate operations such as count, sum, max, min, avg, and many more. It supports Super Aggregation: Rollups, Cube, and Grouping Sets. It supports analytic operations such as lag/lead and row number and more. It also allows custom aggregate and analytic operations.

...The queue is also such a linked list but is paired oppositely so previous queue state goes on the left and next object queued on the right of the new pair, so when the queue is navigated in sequence of that astronomically long bitstring (thats exponential of reusing objects in the acyclicNet), the Nav32 (using linearForward and treeForward for random access) first sees the oldest object queued

Realtime bigdata tool at the bit level based on immutable AVL forest which can be run in memory or, in future versions, as a merkle forest like a blockchain. Main object is a sparse bit string (Bits) that efficiently scales up to 2^63 bits normally compressed as forest has duplicated substrings. Bits objects support reading bit, byte, short, int, or long (Java primitives) at any bit index in 64 bit range. Example: instead of building a class to hold a header and then data, represent all of that as Bits, subranges of them, and ints for sizes of its parts. Expansion ability for other kinds of compression, since Bits is a Java interface. ...

A collection of projects I have developed in the past years. It contains: - a tool to compute height and angle of objects above horizon - a proof of concept of DFT and DWT to reduce audio files - a quantitative library with OOorg interface for Calc

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. ...

HcryptoJ (Historical cryptology in Java) is a Java based programming library for implementing and analyzing historical ciphers. HcryptoJ is designed to support research and teaching in historical cryptography and computer science. Licensed under GPL.

Clados is a java package that implements a multivector in a Clifford Algebra. Algebras (over real numbers) with any signatures may be used. A calculator and associated documentation is also included to help users learn how things work.

Plexus is a Java library with specifications and implementations for generic graph data structures. Like the Java Collections Framework, vertices and edges are containers for arbitrary user-defined objects.

Geoplan-Geospace is a 2D and 3D interactive geometry software to create and manipulate interactive figures for eLearning. It features euclidean geometry objects (lines, circles), numerical functions, numerical sequences, geometrical transformations.

A library of data objects that simulate mathematical neurons, including classic Hodgkin-Huxley neurons and theta neurons.

VisualMaths is a 2D curve drawing program (3D and dynamic curves not yet available). User defines objects (functions,variables,arrays) and assign each object to a curve and an axis. VisualMaths also provides some graphic solvers : minima, maxima.

Java objects that share parts of immutable graphs. Reused subgraphs have directly or indirectly recursive Elements. Selected components get replaced by new counterparts in Context of Mirrors - translation tables. Deep copies are not involved.

Library made with the quantity/formatter pattern. (Currency/CurrencyFormat, Density/DensityFormat, Dimension/DimensionFormat, Distance/DistanceFormat, ElapsedTime/ElapsedTimeFormat, Temperature/TemperatureFormat, Volume/VolumeFormat, Weight/WeightFormat)

JGV is a Java applet that lets you embed movable 3D objects in web pages. Users can rotate, scale, translate, select and annotate the objects interactively. Also, JGV supports XML-based transmission of user events to the source web server over HTTP.

ThreeSpace is a 3D drawing program, or modeller if you will, primarily intended for visualizing and playing with mathematical functions. It allows you to superimpose these or otherwise alter objects in 3D using them.
