Brian and Diez: First of all, thanks for the advice.
Brian: I have installed NumPy and SciPy, but I can't seem to find a wavelet transform there. The main point of this was more to learn C wrapping than to actually get a calculation done. I will probably be starting a PhD soon, doing really heavy computations. If I want to manipulate data (input / results), python is very nice, especially with gnuplot-py. However, heavy calculations should probably be done in C(++), especially as some code for this already exists. I will look into SWIG. Diez: I will look into it. Do you know a good tutorial for this? I found the "standard" tutorial on C extensions, http://www.python.org/doc/ext/intro.html , but as I mentioned, it seems to be a bit complicated to wrap heavy data structures like arrays.
