numpy.polynomial.Polynomial.identity ¶
method
 classmethod Polynomial. identity ( domain = None , window = None ) ¶

Identity function.
If
p
is the returned series, thenp(x) == x
for all values of x. Parameters

 domain {None, array_like}, optional

If given, the array must be of the form
[beg, end]
, wherebeg
andend
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]
, wherebeg
andend
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.
