Legendre Module (:mod:`numpy.polynomial.legendre`)
==================================================

.. versionadded:: 1.6.0

.. currentmodule:: numpy.polynomial.legendre

This module provides a number of objects (mostly functions) useful for
dealing with Legendre series, including a `Legendre` class that
encapsulates the usual arithmetic operations.  (General information
on how this module represents and works with such polynomials is in the
docstring for its "parent" sub-package, `numpy.polynomial`).
