Interfaces to FITPACK routines for 1D and 2D spline fitting
===========================================================

This section lists wrappers for `FITPACK <http://www.netlib.org/dierckx/>`__
functionality for 1D and 2D smoothing splines. In most cases, users are better off
using higher-level routines listed in previous sections.


1D FITPACK splines
------------------

This package provides two sets of functionally equivalent wrappers: object-oriented and
functional.

**Functional FITPACK interface:**


.. autosummary::
   :toctree: generated/

   splrep
   splprep
   splev
   splint
   sproot
   spalde
   splder
   splantider
   insert

**Object-oriented FITPACK interface:**

.. autosummary::
   :toctree: generated/

   UnivariateSpline
   InterpolatedUnivariateSpline
   LSQUnivariateSpline


2D FITPACK splines
------------------

**For data on a grid:**

.. autosummary::
   :toctree: generated/

   RectBivariateSpline
   RectSphereBivariateSpline

**For unstructured data (OOP interface):**

.. autosummary::
   :toctree: generated/

   BivariateSpline
   SmoothBivariateSpline
   SmoothSphereBivariateSpline
   LSQBivariateSpline
   LSQSphereBivariateSpline

**For unstructured data (functional interface):**

.. autosummary::
   :toctree: generated/

   bisplrep
   bisplev
