About NumPy
===========
`NumPy `__ is the fundamental package
needed for scientific computing with Python. This package contains:
- a powerful N-dimensional :ref:`array object `
- sophisticated :ref:`(broadcasting) functions `
- basic :ref:`linear algebra functions `
- basic :ref:`Fourier transforms `
- sophisticated :ref:`random number capabilities `
- tools for integrating Fortran code
- tools for integrating C/C++ code
Besides its obvious scientific uses, *NumPy* can also be used as an
efficient multi-dimensional container of generic data. Arbitrary
data types can be defined. This allows *NumPy* to seamlessly and
speedily integrate with a wide variety of databases.
NumPy is a successor for two earlier scientific Python libraries:
NumPy derives from the old *Numeric* code base and can be used
as a replacement for *Numeric*. It also adds the features introduced
by *Numarray* and can also be used to replace *Numarray*.
NumPy community
---------------
Numpy is a distributed, volunteer, open-source project. *You* can help
us make it better; if you believe something should be improved either
in functionality or in documentation, don't hesitate to contact us --- or
even better, contact us and participate in fixing the problem.
Our main means of communication are:
- `scipy.org website `__
- `Mailing lists `__
- `Numpy Trac `__ (bug "tickets" go here)
More information about the development of Numpy can be found at
http://scipy.org/Developer_Zone
If you want to fix issues in this documentation, the easiest way
is to participate in `our ongoing documentation marathon

Conventions
-----------
Names of classes, objects, constants, etc. are given in **boldface** font.
Often they are also links to a more detailed documentation of the
referred object.
This manual contains many examples of use, usually prefixed with the
Python prompt ``>>>`` (which is not a part of the example code). The
examples assume that you have first entered::
>>> import numpy as np
before running the examples.
