This function returns the value of the nth Hermite polynomial of x. It is defined in terms of the "physicists" Hermite polynomials (see Wikipedia).
Syntax: val = hermiteh(n,x);
Where "n" is the order of the polynomial and "x" is the argument. "x" can be a scalar or an array with up to two dimensions.
Also included is an example script to show one possible use. The image displayed with this file is of the Hermite-Gaussian 3,3 mode and uses hermiteh.m to create it.
This function is expected to be a bit faster for high orders than the submission acknowledged below because it uses the explicit formula and not the recursion relation.

| Version | Published | Release Notes | Action |
|---|---|---|---|
| 1.3.0.0 | The example script was missing a sqrt(2) scaling factor and as a result gave the wrong distribution for the Hermite-Gaussian modes. This change does not affect the calculator itself. Updated to the correct picture of the Hermite-Gaussian 3,3 mode. |
