The octave-forge package is the result of The GNU Octave Repositry project, which is intended to be a central location for custom scripts, functions and extensions for GNU Octave. contains the source for all the functions plus build and install scripts. This is zenity. A set of functions for creating simple graphical user interfaces. It is currently possible to create calendar windows, text entries, file selection dialogs, lists, message windows, icons in the notification area, and windows for large amount of text.

Number::Compare compiles a simple comparison to an anonymous subroutine, which you can call with a value to be tested again. Now this would be very pointless, if Number::Compare didn't understand magnitudes. The target value may use magnitudes of kilobytes (k, ki), megabytes (m, mi), or gigabytes (g, gi). Those suffixed with an i use the appropriate 2**n version in accordance with the IEC standard: http://physics.nist.gov/cuu/Units/binary.html

PDAL is a BSD licensed library for translating and manipulating point cloud data of various formats. It is a library that is analogous to the GDAL raster library. PDAL is focussed on reading, writing, and translating point cloud data from the ever-growing constellation of data formats that are being developed for working with multi-dimensional emitted-pulse scanning systems. While PDAL is not explicitly limited to working with LiDAR data formats, its initial rollout is focused in that area.

A class of units of physical quantities for Ruby. This class covers most functionality of UNIDATA's UDUNITS Library, however, with a more sophisticated handling of string expressions. UDUNITS always decomposes units into the four base units and discards the original string expressions. Therefore, 'hPa' always becomes '100 kg.m-1.sec-1', and 'day' always becomes '86400 sec'. On the other hand, this library tries to keep the original expressions as much as possible by default, while allowing partial to complete decompositions if needed.

SAGA - short hand for "System for Automated Geoscientific Analyses" - is a free, hybrid, cross-platform GIS software. The heart of SAGA is its C++ and thus object oriented Application Programming Interface (API), providing data object definitions and computational methods for raster, vector and tabular data. As a normal user, you will not get into touch with the API. But as an interested scientist or coder you will soon discover its great flexibility.

The SDPARA (SemiDefinite Programming Algorithm PARAllel version) is a parallel version of the SDPA. C++ source codes of the SDPARA are available in this homepage. They form a stand-alone software package for solving SDPs in parallel with the help of MPI (Message Passing Interface) and ScaLAPACK (Scalable LAPACK). However callable libraries of the SDPARA, which could be used combinedly with other C++ programs, are not available. We assume that you know how to use the latest version of the SDPA and MPICH.

This package contains functions to perform Bayesian inference using posterior simulation for a number of statistical models. Most simulation is done in compiled C++ written in the Scythe Statistical Library Version 1.0.3. All models return coda mcmc objects that can then be summarized using the coda package. Some useful utility functions such as density functions, pseudo-random number generators for statistical distributions, a general purpose Metropolis sampling algorithm, and tools for visualization are provided.

sfft is a library to compute discrete Fourier transforms of signals with a sparse frequency domain, using an algorithm that is more efficient than other known FFT algorithms. It was developed by Haitham Hassanieh, Piotr Indyk, Dina Katabi, and Eric Price at the Computer Science and Artifical Intelligence Lab at MIT. Performance optimizations were developed by J. Schumacher at the Computer Science Department of ETH Zurich in 2013.

Solitaire is an encryption system based on a deck of cards by Bruce Schneier. Although it is designed to be worked out by a human, it can work on computers. This is the reference implementation programmed in Perl. The program itself is installed as 'solitaire', and the source code and test vectors are installed in share/doc/solitaire. Please read the web site below before relying on this for real security.

This portable, modular Fortran 90 software package implements the thick-restart Lanczos method, for use with real symmetric or complex Hermitian eigenvalue problems where a small number of eigevalues and eigenvectors are needed, and the matrices involved may be too large to store in computer memory. Most of the arithmetic computations in the software are done through calls to BLAS and LAPACK. The software can be instructed to write checkpoint files so that it can be restarted is a later time.
