This package provides C++ bindings for libframe for dealing with frame files.

LHAPDF provides a unified and easy to use interface to modern PDF sets. It is designed to work not only with individual PDF sets but also with the more recent multiple "error" sets. It can be viewed as the successor to PDFLIB, incorporating many of the older sets found in the latter, including pion and photon PDFs. In LHAPDF the computer code and input parameters/grids are separated thus allowing more easy updating and no limit to the expansion possibilities. The code and data sets can be downloaded together or inidivually as desired. From version 4.1 onwards a configuration script facilitates the installation of LHAPDF.

This is the latest pre-6.0.0 version of LHAPDF.

A Common Data Frame Format for Interferometric Gravitational Wave Detector
has been developed by VIRGO and LIGO. The Frame Library is a software
dedicated to the frame manipulation including file input/output.

LiE is a computer algebra system that is specialised in computations involving (reductive) Lie groups and their representations.

Glue is a collection of utilities for running data analysis pipelines
for online and offline analysis as well as accessing various grid
utilities. It also provides the infrastructure for the segment
database.

MathGL is a cross-platform library for making high-quality scientific graphics. It provides fast data plotting and handling of large data arrays, as well as window and console modes and for easy embedding into other programs. MathGL integrates into FLTK, Qt and OpenGL applications.

This code implements a simple recursive-descent parsing scheme for LIGO_LW
files.

O2scl is a C++ library for object-oriented numerical programming. It
includes interpolation, differentiation, integration, roots of
polynomials, equation solving, minimization, constrained minimization,
Monte Carlo integration, simulated annealing, least-squares fitting,
solution of ordinary differential equations, two-dimensional
interpolation, Chebyshev approximation, unit conversions, and file I/O
with HDF5.

GNU Octave is a high-level language, primarily intended for numerical computations. It provides a convenient command line interface for solving linear and nonlinear problems numerically, and for performing other numerical experiments using a language that is mostly compatible with Matlab.

ParaView is an open-source, multi-platform data analysis and visualization application. Users can quickly build visualizations to analyze their data using qualitative and quantitative techniques. The data exploration can be done interactively in 3D or programmatically using ParaView's batch processing capabilities.

ParaView is an application designed with the need to visualize large data
sets in mind.

ParaView runs on distributed and shared memory parallel as well as single
processor systems and has been successfully tested on Windows, Linux and
various Unix workstations and clusters. Under the hood, ParaView uses the
Visualization Toolkit as the data processing and rendering engine and has a
user interface written using a unique blend of Tcl/Tk and C++.

This package contains some example data for Paraview.

PLplot is a library of functions that are useful for making scientific
plots.

PLplot can be used from within compiled languages such as C, C++,
FORTRAN and Java, and interactively from interpreted languages such as
Octave, Python, Perl and Tcl.

The PLplot library can be used to create standard x-y plots, semilog
plots, log-log plots, contour plots, 3D surface plots, mesh plots, bar
charts and pie charts. Multiple graphs (of the same or different sizes)
may be placed on a single page with multiple lines in each graph.

A variety of output file devices such as Postscript, png, jpeg, LaTeX
and others, as well as interactive devices such as xwin, tk, xterm and
Tektronics devices are supported. New devices can be easily added by
writing a small number of device dependent routines.

There are almost 2000 characters in the extended character set. This
includes four different fonts, the Greek alphabet and a host of
mathematical, musical, and other symbols. Some devices supports its own
way of dealing with text, such as the Postscript and LaTeX drivers, or
the png and jpeg drivers that uses the Freetype library.

This package provides the shared libraries for PLplot.

Praat is an open-software tool for the analysis of speech in phonetics.
Through its graphical interface, several speech analysis functionalities
are available: spectrograms, cochleograms, and pitch and formant extraction.
Articulatory synthesis, as well as synthesis from pitch, formant, and
intensity are also available. Other features are segmentation, labelling
using the phonetic alphabet, and computation of statistics.
Praat is configurable and extensible through its own scripting language and has
provisions for communicating with other programs.

Pythia can be used to generate high-energy-physics ‘events’, i.e. sets of outgoing particles produced in the interactions between two incoming particles. The objective is to provide as accurate as possible a representation of event properties in a wide range of reactions, within and beyond the Standard Model, with emphasis on those where strong interactions play a role, directly or indirectly, and therefore multihadronic final states are produced. The physics is then not understood well enough to give an exact description; instead the program has to be based on a combination of analytical results and various QCD-based models. Extensive information is provided on all program elements: subroutines and functions, switches and parameters, and particle and process data. This should allow the user to tailor the generation task to the topics of interest.
