Python
Some of the demo programs used in the course, particularly those using a
GUI, are written in python. If you want to try this (open source, nice
and free alternative to matlab), some tips are gathered below. Please
note there is absolutely no requirement to learn about python for the
course, the information is simply provided to give a few hints to those
who want to try it.
If you are using linux (for instance ubuntu or debian), please
use the package manager provided by the system (like synaptic under
ubuntu). This will make your life considerably simpler, you just have to
mark the different packages below and the system will do the
installation for you.
If you are using windows, you can get all packages in one bundle by installing Python(x,y), choose Full installation after download.
If you are using macOSX, a corresponding bundle is provided by Enthought
(also available for other platforms). I have not tested it myself, but
it is recommended by many others. You should probably try the Academic
or Trial version (the others cost money).
The packages can also be downloaded from their respective web sites (where you may find additional documentation):
- python
(the language itself; use the latest v2.x (like 2.6 or 2.7), several of
the packages below like numpy have not been properly ported to python3
yet)
- matplotlib (provides most of the "matlab look-a-like" facilities (some tips here), usually pulls with it numpy and scipy below automagically)
- numpy (basic numerical calculations, particularly matrices)
- scipy (scientific libraries, for instance special functions and signal processing)
- wxpython (for GUI-programming, slightly more advanced, also look at tkinter which is bundled with python from scratch)
- mayavi (for 3D-plots using VTK, advanced but powerful)
