fityk 0.8.8

 Longer version: fityk is a program for nonlinear fitting of analytical functions (especially peak-shaped) to data (usually experimental data). There are also people using it to remove the baseline from data, or to display data only.

It is reportedly used in crystallography, chromatography, photoluminescence and photoelectron spectroscopy, infrared and Raman spectroscopy, to name but a few.

Fityk knows about common peak-shaped functions (Gaussian, Lorentzian, Voigt, Pearson VII, bifurcated Gaussian, EMG, Doniach-Sunjic, etc.) and polynomials. It also supports user-defined functions.

Fityk offers intuitive graphical interface (and also command line interface), variouse optimization methods (standard Marquardt least-square algorithm, Genetic Algorithms, Nelder-Mead simplex), equality constraints, modelling error of x coordinate of points (eg. zero-shift of instrument), handling series of datasets, automation of common tasks with scripts, and more.

  Octave-Forge R2009-06-07


 Octave-Forge is a central location for the collaborative development of packages for GNU Octave.

The Octave-forge packages contains the source for all the functions and are designed to work with the Octave package system. In general the packages are designed to work with the latest development version of Octave, but it should be possible to use most packages with earlier versions.



New release of Octave-forge To celebrate the release of Octave 3.2, a new release of the package have been made. This should be compatible with the latest version of Octave.

  New release of Octave-forge Notable changes in this release include:

     * image: removel of imread and imwrite as they have been moved to core Octave. New functions: entropyfilt, ordfiltn, rangefilt, stdfilt
     * control: include functions previously shipped with core Octave.
     * finance: include functions previously shipped with core Octave.
     * general: include a parallel version of cellfun: parcellfun.
     * nnet: new functions: dividerand, ind2vec, mapstd, vec2ind.
     * nan: support complex data.
     * new packages: nurbs, oct2mat, bugfix, simp, quaternion.
     * general bug fixes and improvements all over the place.

ROOT 5.24/00

Why ROOT?

Having had many years of experience in developing the interactive data analysis systems PAW and PIAF and the simulation package GEANT, we realized that the growth and maintainability of these products, written in FORTRAN and using some 20 year old libraries, had reached its limits. Although still very popular, these systems do not scale up to the challenges offered by the LHC, where the amount of data to be simulated and analyzed is a few orders of magnitude larger than anything seen before.

It became time to re-think our approach to large scale data analysis and simulation and at the same time we had to profit from the progress made in computer science over the past 15 to 20 years. Especially in the area of Object-Oriented design and development. Thus was born ROOT.

We started the ROOT project in the context of the NA49 experiment at CERN. NA49 generates an impressive amount of data, about 10 Terabytes of raw data per run. This data rate is of the same order of magnitude as the rates expected to be recorded by the LHC experiments. Therefore, NA49 was the ideal environment to develop and test the next generation data analysis tools and to study the problems related to the organization and analysis of such large amounts of data.

With ROOT we try to provide a basic framework that offers a common set of features and tools for all domains of High Energy Physics computing.

Currently the emphasis of ROOT is on the data analysis domain but thanks to the approach of loosely coupled object-oriented frameworks the system can easily be extended to other domains, like simulation, reconstruction, event displays and DAQ.

We believe that ROOT is an ideal environment to introduce physicists quickly to the new world of Objects and C++.

What is ROOT?

The ROOT system provides a set of OO frameworks with all the functionality needed to handle and analyze large amounts of data in a very efficient way. Having the data defined as a set of objects, specialized storage methods are used to get direct access to the separate attributes of the selected objects, without having to touch the bulk of the data. Included are histograming methods in an arbitrary number of dimensions, curve fitting, function e
