Interpolation (:mod:`scipy.interpolate`)
========================================

.. currentmodule:: scipy.interpolate

Sub-package for objects used in interpolation.

As listed below, this sub-package contains spline functions and classes,
one-dimensional and multi-dimensional (univariate and multivariate)
interpolation classes, Lagrange and Taylor polynomial interpolators, and
wrappers for `FITPACK <http://www.netlib.org/dierckx/>`__
and DFITPACK functions.
