SciPy: A scientific computing package for Python
================================================

Documentation is available in the docstrings and
online at https://docs.scipy.org.

Contents
--------
SciPy imports all the functions from the NumPy namespace, and in
addition provides:

Subpackages
-----------
Using any of these subpackages requires an explicit import. For example,
``import scipy.cluster``.
