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.

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

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!

General Number Field Sieve implementation

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

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

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

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.

This program will enable you to find every solar eclipse in between about 2500 BC to 3500 AD. The central line can be displayed graphically and saved as a JPEG or PNG image file or as a PDF document.

It is often necessary to smooth high frequency fluctuations out of data streams sequenced by time, position, etc. The 'smooth' utility applies such smoothing using the wavelet algorithm. This implementation of wavelet smoothing was optimized for use in a data stream. It was adapted from HMMSeg Wavelet.Java by Thomas E. Wilson, University of Michigan. HMMSeg Wavelet.Java was written by Andrew Hemmaplardh, University of Washington. http://noble.gs.washington.edu/proj/hmmseg/ Unsupervised segmentation of continuous genomic data, Bioinformatics 2007 23:1424-1426 See the above references for a more thorough description of the principles behind wavelet smoothing.

Trad4 is a fully concurrent, thread safe, graph-based programming language that scales linearly on multiple cores. It is initially intended for deployment in the financial industry to model real-time risk.

The SNP ratio test can assess significance of enrichment of significant associations in genome-wide association studies. Tests can be applied to pathways such as KEGG/GO, or user-defined pathways to test specific hypotheses. See link below for more.

The Perl 3D-extension of MFPic LaTeX package aimed to high quality draw of spatial objects, such as vectors, curves, bounded surfaces.

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.

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

The Thot toolkit repository has moved to http://daormar.github.io/thot/ Thot is a toolkit for statistical machine translation. The new Thot toolkit includes fully automatic and interactive machine translation, incremental training of statistical models, parallel estimation, ...

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

The pf2html project adds functionality to LATEX2HTML such that LATEX documents written with pf.sty can be viewed in a web browser up to the desired level of detail for each branch of a structured proof.

This program converts calculator-style ASCII math notation (the same that ASCIIMathML uses) to Spanish Braille mathematics notation (not Nemeth Code).

Symbolic Algebra using Perl

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

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).
