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.

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

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

Singular is a Computer Algebra system for polynomial computations with emphasis on the special needs of commutative algebra, algebraic geometry, and singularity theory.

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!

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.

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

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

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).

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.

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).

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).

* Introduction: - This Module is a Library based Perl code. - The library provide: - Convert INFIX expressions to POSTFIX; - Convert POSTFIX expressions to INFIX and; - Perform POSTFIX context validations. - Context validation can be implemented in item selection routines or data context validation, when it is possible to identify data to be selected or ignored in some data analysis process. * NOTE: - Before any implementation, we recommend details in WIKI (https://sourceforge.net/p/csi-math-notation-postfixinfix/wiki/) or the CPAN Perl Modules, see: https://metacpan.org/pod/Math::Notation::PostfixInfix * Support: The Support Service is FREE. Do you need support? Open a ticket and I will get back to you as soon as possible. * Professional Services: Do you need any FREE professional services to use? Open a ticket as "FAQ request" and I will get back to you as soon as possible. i.e: subject:

Calcgui is a graphical calculator written in Perl. It's very lightweight and works with Perl/Tk. It is able to calculate allmost any function with 1 variable and is also able to graph them.

Preference (or approval) ballot tabulation to select winner(s) of election contests or rank decisions. Uses dropping cost minimization to combine two Condorcet methods: Cloneproof Schwartz Sequential Dropping and Tideman's Ranked Pairs.

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

Simple Dijkstra shortest path implementation - for learning and teaching

Software that implements the tabular method developed by Steve Keen for developing a set of differential equations to model monetary flows in economic analysis, modeling and simulation.

The software has been moved to https://github.com/upriss/fcastone

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.
