Polynomial.identity()

classmethod Polynomial.identity(domain=None, window=None) [source]

Identity function.

If p is the returned series, then p(x) == x for all values of x.

Parameters:

Parameters:	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 Series of representing the identity.

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

Series of representing the identity.
