def hermite ( n , monic = False )

Physicist's Hermite polynomial.

Defined by

H_{n} (x) = (- 1)^{n} e^{x^{2}} \frac{d ^{n}}{d x ^{n}} e^{- x^{2}};

$H_{n}$ is a polynomial of degree $n$ .

n : int: Degree of the polynomial.
monic : bool, optional: If True, scale the leading coefficient to be 1. Default is False.

The polynomials $H_{n}$ are orthogonal over $(- \infty, \infty)$ with weight function $e^{- x^{2}}$ .
