Open Source Libraries

This library is used to calculate the position of a satellite or the moon on any geographical location on the earth's surface. The Library is writte in C++ and OOP. The Actual Status of the Library can download from the svn-repository. On my website oe5tpo.com can you find infos about satpos, but this infos are all in German!

Create a sun, spin some asteroids around it, and watch them collide and form planets. An N-Point Gravity Simulator is a realistic simulation in which all points attract each other: even the smallest asteroid has its own gravitational field that can affect even a large sun far away from it. Can be reused as a library for making games. If used as library, license is GNU LGPLv3, otherwise it's GNU GPLv3.

GPX is mainly a physics engine, written in C++, focused on real time simulations. Project also provides a graphics library, built on top of SFML. Physics part is independent from graphics library and can be used with any other front-end.

RooCARDS is a set of C++ classes written for the ROOT analysis framework which interface ROOT to the Stuttgart Neural Network Simulator (SNNS). This interface is based on a concept originally developed by Professor Yibin Pan at the UW-Madison.

Structures of arrays (SoA) are generally faster than arrays of structures (AoS) while AoS are more handy. This project (SoAx) combines the advantages of both. By means of C++(11) meta-template programming SoAx achieves maximal performance (efficient use of vector units and cache of modern CPUs) while providing a very convenient user interface (including object-oriented element handling) and flexibility. It has been designed to handle list-like sets of particles (similar to struct {int id; double[3] pos; float[3] vel;};) in the context of high-performance numerical simulations. It can be applied to many other problems. Please check the sample file main.cpp to see examples of code that you can write with SoAx.

The library provides an implementation of dimensioned values for Ada. Unit checks are made at run-time, if not optimized out by the compiler. SI and irregular measurement units are supported. Shifted units like degrees Celsius are supported too. Conversions from and back to strings are provided for all various irregular units. An extensive set of GTK widgets for dealing with dimensioned values is included, though use of GTK is not mandatory for the rest of the library.

cuLsoda is an implementation of the Livermore Solver for Ordinary Differential Equations with Automatic switching for stiff and non-stiff problems (LSODA), written in NVIDIA's C for CUDA GPGPU API. NOTE: This repository is now deprecated and replaced by a new one at GitHub: https://github.com/Celemourn/cuLsoda

A MatLab toolbox with many simple and useful functions for analyzing data from Cluster, Champ and the future Swarm missions. Other functions for space science, magnetospheric and ionospheric research are included. The toolbox is designed to be as simple as possible. Each function can be learned and used individually. Check the webpage for the list of functions: http://eugen-library.sourceforge.net/

A C library for digital signal filtering
