`scipy.special.``eval_laguerre`(n, x, out=None) = <ufunc 'eval_laguerre'>

  Evaluate Laguerre polynomial at a point.

  The Laguerre polynomials can be defined via the confluent hypergeometric function \({}_1F_1\) as

  \[L_n(x) = {}_1F_1(-n, 1, x).\]

  When \(n\) is an integer the result is a polynomial of degree \(n\).

  Parameters: | n : array_like Degree of the polynomial. If not an integer the result is determined via the relation to the confluent hypergeometric function. x : array_like Points at which to evaluate the Laguerre polynomial
  Returns: | L : ndarray Values of the Laguerre polynomial
