FNHnreturns the value of the Hermite polynomial of ordernofx,Hn(x).Nmust be positive or zero.
Errors
FNHncauses an HTBasic error if its arguments are not of the types listed in the USAGE section, above, ifnis negative, or if the polynomial's absolute value would be larger than MAXREAL, the largest value representable.
Note
Forn> 12, the algorithm used computes the value ofHnusing a recursion from the values ofH11 andH12. The computation time increases withn-11 and the computation accuracy decreases withn-11.
