Open Source Perl Mathematics Software

Arabeyes is a Meta project that is aimed at fully supporting the Arabic language in the Unix/Linux environment. It is designed to be a central location to standardize the Arabization process. Arabeyes relies on voluntary contributions.

The netCDF Operators, or NCO, are a suite of file operators which facilitate manipulation and analysis of self-describing data stored in the (freely available) netCDF and HDF formats. Volunteers welcome! See homepage for details and download links.

The PDL module gives standard perl the ability to COMPACTLY store and SPEEDILY manipulate the large N-dimensional data sets that are the bread and butter of scientific computing.

The only open source counter to count any items the simplest and easiest way with the keyboard, or the mouse specifically on images. After associating a key to each item, or a predefined graphical symbol for images, pressing the key or clicking on the image increments its associated counter, and displays (for the images) the symbol at the mouse's pointer location. Such a project is so simple a child could use it!

This project is for maintaining a linux system that concentrates on math, logic, and geometry related softwares.

GGNFS is an open source implementation of General Number Field Sieve algorithm for factoring integers.

Why is it quicker to express simple equations in plaintext that it is to write the equivalent LaTeX? Easylatex is a preprocessor to make writing LaTeX much quicker. Project activity mode (http://bayleshanks.com/pamv1 ): sporadic

GladTeX is a preprocessor that enables the use of LaTeX maths within HTML code. The maths, embedded in <eq>..</eq> tags, as if within $$..$$ in LaTeX, is fed through latex and replaced by images. Additionally, alt-tags are auto-generated which display the LaTeX-equations when the HTML is viewed e.g. with a text mode browser or by someone with vision loss. The project home has moved, please visit https://humenda.github.io/GladTeX

General Number Field Sieve implementation

Gplot provides a convenient front-end for gnuplot. It accepts a large set of options to generate a single plot of one or more sets of data (overlaid as necessary).

A collection of modeling tools for system comprehension. Includes 1) DEMOS2K - a semantically justified version of DEMOS 2) SAVANT - a tool for evaluating system availability 3) GOLDSTAR - an arbitrary reward calculation system.

Corbata is a set of statistical tools that can be used to analyze the core microbiome across a set of samples.

A neural network package for Octave! Goal is to be as compatible as possible to the one of MATLAB(TM).

Web based PHP interface to communicate to Maxima computer algebra system in the server. It takes user input, send it to Maxima, and show the output back to website. It could send almost any commands including 'plot2d' and 'plot3d' to plot graphs.

Statistics modules in Perl Data Language, with a quick-start guide for non-PDL people. They make the PDL shell work like R, but with PDL threading (fast automatic iteration) of procedures including t-test, linear regression, and k-means clustering.

STATPerl (Statistics with Perl) is a free Statistical Software based on Perl. Perl source codes for various statistical analysis are given with it. User can add new analysis and edit existing one. An inbuilt Perl IDE comes with it.

A collection of many different perl-scripts doing math-stuff, including date and time scripts.

Average is a simple and fast command-line Perl utility for calculating basic statistics on a list of numbers (one number per line). It works as a traditional Unix filter and can be used as part of those greatly useful chains of piped commands. It calculates average (arithmetic mean), standard deviation, median, total sum, minimum and maximum values present, and shows the number of processed numbers. Entry can by a text file (any column can be specified, default is the first) or directly in the terminal if Average is run without specifying a file -- in which case, input can be terminated by pressing Ctrl-D. It is possible to choose the output of a single statistic (just the value, no labels), instead of the fully detailed output (default).

FreeNorm is a cross-tabulation web application adapted from SurveyComplete's real-time reporting system. Currently it can run tabs on extremely large datasets, export to Excel, read ASCII data, and understand table definitions in the UNCLE tab language.

LavaRnd is a random number generator that converts a digitized chaotic source (such as a lens capped web camera) into cryptographically strong random numbers. LavaRnd comes with both an APIs (currently C and Perl) as well as a number of demos.

Portable software related to Mersenne numbers. Useful to automate certain tasks related to GIMPS (www.mersenne.org) for computers that cannot run the GIMPS software for whatever reason. Much of the code has been in use since 1990 or so by a few people. The project web site at https://mers.sourceforge.io/mersenne.html has data about Mersenne numbers from many people generated by this and other software, notably from the GIMPS project.

Symbolic Algebra using Perl

Linear Programming (LP) has been used in the case of the Federalist Papers whose authorship had been disputed. The task here will be to use the Cell Broadband Engine to do likewise with papers whose authorship is disputed.

A Perl Extension for modeling enzymatic (biochemical) reaction networks

blat(mat) is a Braille to print translator for maths. It takes a Spanish Six-dot Mathematical Braille (not Nemeth Code) text and converts it to an HTML file ready to be translated into XHTML+MathML by ASCIIMathML (javascript).
