# scipy.special.genlaguerre

scipy.special.genlaguerre(n, alpha, monic=False)

  Generalized (associated) Laguerre polynomial.

  Defined to be the solution of

  \[x\frac{d^2}{dx^2}L_n^{(\alpha)} + (\alpha + 1 - x)\frac{d}{dx}L_n^{(\alpha)} + nL_n^{(\alpha)} = 0,\]

  where \(\alpha > -1\); \(L_n^{(\alpha)}\) is a polynomial of degree \(n\).

  Parameters
    n int

      Degree of the polynomial.

    alpha float

      Parameter, must be greater than -1.

    monic bool, optional

      If True, scale the leading coefficient to be 1. Default is False.

  Returns
    L orthopoly1d

      Generalized Laguerre polynomial.

    Laguerre polynomial.

  Notes

  For fixed \(\alpha\), the polynomials \(L_n^{(\alpha)}\) are orthogonal over \([0, \infty)\) with weight function \(e^{-x}x^\alpha\).

  The Laguerre polynomials are the special case where \(\alpha = 0\).
