numpy.polynomial.laguerre.Laguerre

class numpy.polynomial.laguerre.Laguerre(coef, domain=None, window=None)

A Laguerre series class.

The Laguerre class provides the standard Python numerical methods ‘+’, ‘-‘, ‘*’, ‘//’, ‘%’, ‘divmod’, ‘**’, and ‘()’ as well as the attributes and methods listed in the ABCPolyBase documentation.

Parameters:

coef : array_like

Laguerre coefficients in order of increasing degree, i.e, (1, 2, 3) gives 1*L_0(x) + 2*L_1(X) + 3*L_2(x).

domain : (2,) array_like, optional

Domain to use. The interval [domain[0], domain[1]] is mapped to the interval [window[0], window[1]] by shifting and scaling. The default value is [0, 1].

window : (2,) array_like, optional

Window, see domain for its use. The default value is [0, 1].

New in version 1.6.0.
