matplotlib is a python 2D plotting library which produces publication quality figures in a variety of hardcopy formats and interactive environments across platforms. matplotlib can be used in python scripts, the python and ipython shell (ala MATLAB®* or Mathematica®†), web application servers, and six graphical user interface toolkits.

Fascinating and absorbing. Pretty much the first question: why aren't old versions of Mathematica made open source? His answer is smart.

… handelt vor allem von einigen Teilbereichen des Informatikstudiums.

Jedoch fließen auch Bereiche in diese Webseite ein, die nicht zum Grundstudium, sondern zum Haupstudium gehören, wie Animation und Neuronale Netze. Der Bereich Latex gehört gar nicht zum Informatikstudium, sondern ist allgemeiner Natur.

SciPy (pronounced "Sigh Pie") is open-source software for mathematics, science, and engineering. It is also the name of a very popular conference on scientific programming with Python. The SciPy library depends on NumPy, which provides convenient and fast N-dimensional array manipulation. The SciPy library is built to work with NumPy arrays, and provides many user-friendly and efficient numerical routines such as routines for numerical integration and optimization. Together, they run on all popular operating systems, are quick to install, and are free of charge. NumPy and SciPy are easy to use, but powerful enough to be depended upon by some of the world's leading scientists and engineers. If you need to manipulate numbers on a computer and display or publish the results, give SciPy a try!
