Chebyshev Module (numpy.polynomial.chebyshev)
New in version 1.4.0.
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).
