numpy.polynomial.polynomial.Polynomial

class numpy.polynomial.polynomial.Polynomial(coef, domain=None, window=None)

A power series class.

The Polynomial class provides the standard Python numerical methods ‘+’, ‘-‘, ‘*’, ‘//’, ‘%’, ‘divmod’, ‘**’, and ‘()’ as well as the attributes and methods listed in the ABCPolyBase documentation.

Parameters:

coef : array_like

Polynomial coefficients in order of increasing degree, i.e., (1, 2, 3) give 1 + 2*x + 3*x**2.

domain : (2,) array_like, optional

Domain to use. The interval [domain[0], domain[1]] is mapped to the interval [window[0], window[1]] by shifting and scaling. The default value is [-1, 1].

window : (2,) array_like, optional

Window, see domain for its use. The default value is [-1, 1].

New in version 1.6.0.
