numpy.polynomial.polynomial.Polynomial.basis¶

method

classmethod Polynomial.basis(deg, domain=None, window=None)[source]¶

Series basis polynomial of degree deg.

Returns the series representing the basis polynomial of degree deg.

New in version 1.7.0.

Parameters

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