29.9 Mathematical functions for floating-point types [c.math]
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 respective arguments
n and x.
Returns: 
Hn(x)=(−1)nex2dndxne−x2
where
n is n and
x is x.
Remarks: 
The effect of calling each of these functions
is implementation-defined
if n >= 128.
