Install scipy module for Python (optional)

The module named scipy (Scientific Python) is not necessary for the Gildas-Python binding, but it provides useful functionalities you may want. The build and installation process is exactly the same as for NumPy:

1. Download scipy from: http://www.scipy.org/Download

2. Unpack and compile scipy:

   cd <compilation-directory>
   tar xvzf scipy-0.7.1.tar.gz
   cd scipy-0.7.1
   python setup.py build --fcompiler=<compiler>
   

3. Install:

   python setup.py install [--prefix=/some/custom/installation/prefix]
   

   If you provide a custom installation path (-prefix), use the same as for NumPy: you will not have to augment again the $PYTHONPATH for this second module.

4. Check the installation:

   import scipy
   scipy
   scipy.__version__
   from scipy.special import jn
   

   (the last line tries to import the Bessel functions named jn).
