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``.
