numpy.polynomial.Polynomial.basis

method

classmethod Polynomial. basis ( deg , domain = None , window = None )

Series basis polynomial of degree deg .

Returns the series representing the basis polynomial of degree deg .

New in version 1.7.0.

Parameters
deg int

Degree of the basis polynomial for the series. Must be >= 0.

domain {None, array_like}, optional

If given, the array must be of the form [beg, end] , where beg and end are the endpoints of the domain. If None is given then the class domain is used. The default is None.

window {None, array_like}, optional

If given, the resulting array must be if the form [beg, end] , where beg and end are the endpoints of the window. If None is given then the class window is used. The default is None.

Returns
new_series series

A series with the coefficient of the deg term set to one and all others zero.
