# scipy.special.eval_hermitenorm

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

  Evaluate probabilist’s (normalized) Hermite polynomial at a point.

  Defined by

  \[He_n(x) = (-1)^n e^{x^2/2} \frac{d^n}{dx^n} e^{-x^2/2};\]

  \(He_n\) is a polynomial of degree \(n\). See 22.11.8 in [AS] for details.

  Parameters:
    n array_like

      Degree of the polynomial

    x array_like

      Points at which to evaluate the Hermite polynomial

    out ndarray, optional

      Optional output array for the function values

  Returns:
    He scalar or ndarray

      Values of the Hermite polynomial
