Summary
-------
Description
...........
**NIFTY**, "\ **N**\umerical **I**\nformation **F**\ield **T**\heor\ **y**\ ",
is a versatile library designed to enable the development of signal inference
algorithms that operate regardless of the underlying spatial grid and its
resolution. Its object-oriented framework is written in Python, although it
accesses libraries written in Cython, C++, and C for efficiency.
NIFTY offers a toolkit that abstracts discretized representations of continuous
spaces, fields in these spaces, and operators acting on fields into classes.
Thereby, the correct normalization of operations on fields is taken care of
automatically without concerning the user. This allows for an abstract
formulation and programming of inference algorithms, including those derived
within information field theory. Thus, NIFTY permits its user to rapidly
prototype algorithms in 1D, and then apply the developed code in
higher-dimensional settings of real world problems. The set of spaces on which
NIFTY operates comprises point sets, *n*-dimensional regular grids, spherical
spaces, their harmonic counterparts, and product spaces constructed as
combinations of those.

### Description
**NIFTY**, "**N**umerical **I**nformation **F**ield **T**heor**y**", is
a versatile library designed to enable the development of signal
inference algorithms that operate regardless of the underlying spatial
grid and its resolution. Its object-oriented framework is written in
Python, although it accesses libraries written in Cython, C++, and C for
efficiency.
NIFTY offers a toolkit that abstracts discretized representations of
continuous spaces, fields in these spaces, and operators acting on
fields into classes. Thereby, the correct normalization of operations on
fields is taken care of automatically without concerning the user. This
allows for an abstract formulation and programming of inference
algorithms, including those derived within information field theory.
Thus, NIFTY permits its user to rapidly prototype algorithms in 1D, and
then apply the developed code in higher-dimensional settings of real
world problems. The set of spaces on which NIFTY operates comprises
point sets, *n*-dimensional regular grids, spherical spaces, their
harmonic counterparts, and product spaces constructed as combinations of
those.
### Class & Feature Overview
The NIFTY library features three main classes: **spaces** that represent
certain grids, **fields** that are defined on spaces, and **operators** that
apply to fields.
* `Spaces <http://www.mpa-garching.mpg.de/ift/nifty/space.html>`_
* ``point_space`` - unstructured list of points
* ``rg_space`` - *n*-dimensional regular Euclidean grid
* ``lm_space`` - spherical harmonics
* ``gl_space`` - Gauss-Legendre grid on the 2-sphere
* ``hp_space`` - `HEALPix <http://sourceforge.net/projects/healpix/>`_
