A package to read definitions of in-memory Mathematica functions with ease. It does approximately the same thing as

`GeneralUtilities`PrintDefinitions`

, which however is only available for Mathematica 10 and later.

TensoriaCalc tackles (semi-)Riemannian tensor calculus problems encountered in general relativity, cosmology, and field theory. Currently, it calculates geometric objects – Christoffel symbols, the Riemann curvature tensor, Ricci tensor and scalar, etc. – given a metric and the relevant coordinates; and performs basic operations such as covariant derivatives of tensors.

A System for Computer Supported Mathematical Theorem Proving and Theory Exploration
Theorema was conceived and initiated around 1995 by Bruno Buchberger and reflects his view of "doing mathematics". It is being developed under his guidance by the Theorema Working Group at the Research Institute for Symbolic Computation, Johannes Kepler University, Linz – Hagenberg, Austria.

TIDES is a free software to integrate numerically Ordinary Differential Equations by using a Taylor Series method. It consists on a C (Fortran) library, libTIDES, and a Mathematica package, MathTIDES.

Tunnel is a set of scripts that simplify launching remote Mathematica kernels where all established MathLink connections are automatically tunneled through a secure shell connection (SSH).

Unzips zip archives. Unzip is similar to the Mathematica

`ExtractArchive`

function, except that Unzip prints the file names (using `Print`

or `PrintTemporary`

) while unzipping.

This is a google-code-prettify extension for highlighting Wolfram Language (Mathematica) source code on the web.

This is a standalone parser library for Mathematica (Wolfram Language). The code for the parser is extracted from the Mathematica IntelliJ Plugin. All dependencies to the IntelliJ Platform are included and it can be used as command-line program without a running IntelliJ IDEA.

HTTP server implemented in Wolfram Language. It evaluates Wolfram Language expressions sent to it via post requests and returns the result.

A Wolfram Language client for the XML-RPC WordPress API.

WuRittSolva is a standard application package for computer algebra system Mathematica(TM) developed by Liu Hua-Shan for mechanization mathematics education purpose at present. It introduces the Wu-Ritt Well-Order Principle and Zero-Decompostion Theorem as its key theory considering points, and has implemented the most operation for normal polynomials processing, such as fixing CLASS, MAIN VARIABLE, SEPARANT, POLYNOMIAL RANK, BASIC SET, CHARACTERISTIC SET and so on. What is more, it supplies smart functions for elementary geometry theorems proving, promising theorem proving in a smart way. It strongly advises that the polynomials appearing for functions in WuRittSolva are belong to polynomial ring K[u_1,u_2,...,u_n;x_1,x_2,...,x_n] such that... Read more.

Set of packages enhancing capabilities of Wolfram Workbench. Features include, inter alia, creating cross-version compatible documentation and including, in build scripts, test suite runs in multiple Mathematica versions.

xAct is a suite of free and actively maintained packages for tensor computer algebra in Mathematica. xAct implements state-of-the-art algorithms for fast manipulations of indices and has been modelled on the current geometric approach to General Relativity. It is highly programmable and configurable. Since its first public release in March 2004, xAct has been intensively tested and has solved a number of hard problems in GR.

xCellerator is a Mathematica package designed to aide biological modeling via the automated conversion of chemical reactions into ODEs and their subsequent solution via numerical integration.

LinearModelFit alternative, that allows to fit to data with X and Y errors. Based on York 2004:

A Mathematica package that contains functions for performing triangle-wye (also delta-wye or ΔY) and wye-triangle (also wye-delta or YΔ) transforms on simple undirected graphs.
