Polynomial Module (:mod:`numpy.polynomial.polynomial`)
======================================================

.. versionadded:: 1.4.0

.. currentmodule:: numpy.polynomial.polynomial

This module provides a number of objects (mostly functions) useful for
dealing with Polynomial series, including a `Polynomial` 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`).
