> This is a C++ template class library to perform matrix calculations, just like built-in data types, with ease and efficiency in your programs. It supports most of the matrix calculations like arithmetic operations, sub-matrix operations, inversion, various matrix decompositions, solution of simultaneous linear equations, eigen value and eigen vector problem, and much more. Full source code is included with the package.>

RF21 for Windows is a scientific calculator, plotter, programming and numeric system in one. It allows for permanent installation of a user's own commented functions and libraries. Such user functions may have one or several arguments and values. Works as an archive at the same time, with integrated searchable database, to let you find and reuse materials created years ago. Each function self-reassembles when its name is called, autonomously searching the libraries for all components needed. Predefined functions include gamma, zeta, psi and Bessel functions, error integral, cumulative Binomial distribution and more. On top of these and the user libraries, the program's numeric and plotting capabilities can be used, including: Numeric derivation and integration, Monte Carlo simulations, linear equations, matrix inversion and eigenvalues, nonlinear equation systems, n-dimensional function minimizer (Dennis & Schnabel method), Runge Kutta method for (systems of) differential equations, accelerated summation of series. Fraction reckognizer. Fast screenplots and an environment for designing printable plots, which may as well be exported to -.GIF and -.BMP files. Ample support for both simple and parametric plots, composition of several curves into one picture, drawing of directional or vector fields. Comes with standard libraries covering areas of science and mathematics. Some 200 standard functions, see author's homepage for a systematic reference of these.

3D Browser Light License: Freeware

3D Browser Light is a file explorer, which makes viewing, editing and organizing your images, 3D files and audio files easier. For each directory, 3D Browser Light displays high quality thumbnails for each recognized files, computed in a background thread. 3D Browser Light recognized more than 60 images formats, a lot of 3D formats and most of audio files. Several customizable displays modes, sorts modes and files filters makes browsing directories very comfortable. Images or scenes can viewed or edited with the 3D Browser Light viewers or in an external application, using the fast application access toolbar, drag & drop, or the application selection dialog. Each file has its own property sheet which contains information about author, title, legend, description, keywords. This sheet contains also taking-picture condition information (for images issued from a digital camera) or faces, points materials information for 3D files. You can retrieve your files entering one of these specifics information, using the search feature. 3D Browser Light has an image viewer and an OpenGL viewer for an high-quality display of your images and 3D scenes. Viewers include slides show feature and navigation features to display quickly files contained in the directory. The image viewer can display the image or the alpha channel. It allows convertion, and offers basics editings features (rotate, flip, color inversion...). The OpenGL viewer clearly shows scene hierarchy and materials. It has several rendering mode (wireframed flatted, smoothed, smoothed/wireframed...) and displays textures when they exist. Point of view is defined using the display features (zoom, pan, auto zoom...) and can be used to update the current scene thumbnail or as the default point of view for thumbnails computation. 3D Browser Light also allows playing audio files really easily. It displays useful information for MP3 files (author, title, length...) in the tooltips.
