``` cpp

double hermite(unsigned n, double x);
|

float hermitef(unsigned n, float x);

long double hermitel(unsigned n, long double x);

*Effects:* These functions compute the Hermite polynomials of their
|
| 10 |
+
respective arguments `n` and `x`.
|
| 11 |
+
|
| 12 |
+
*Returns:* $$%
|
| 13 |
+
\mathsf{H}_n(x) =
|
| 14 |
+
(-1)^n e^{x^2} \frac{ \mathsf{d} ^n}
|
| 15 |
+
{ \mathsf{d}x^n} \, e^{-x^2}
|
| 16 |
+
\;$$ where n is `n` and x is `x`.
|
| 17 |
+
|
| 18 |
+
*Remarks:* The effect of calling each of these functions is
|
| 19 |
+
*implementation-defined* if `n >= 128`.
