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`).
