Chebyshev Module (:mod:`numpy.polynomial.chebyshev`) ==================================================== .. versionadded:: 1.4.0 .. currentmodule:: numpy.polynomial.chebyshev This module provides a number of objects (mostly functions) useful for dealing with Chebyshev series, including a `Chebyshev` 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`).
