numpy.polynomial.laguerre.Laguerre.identity

method

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

Identity function.

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

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.
