Hn
Hermite polynomial.
 
Loading        LOADSUB ALL FROM "HERMITE.HTS"
or LOADSUB FROM "MATHLIB.HTS"
 
Usage                INTEGER N
REAL X,Y
Y=FNHn(N,X)
 
Description                
FNHn returns the value of the Hermite polynomial of order n of x, Hn(x). N must be positive or zero.
 
Errors                
FNHn causes an HTBasic error if its arguments are not of the types listed in the USAGE section, above, if n is negative, or if the polynomial's absolute value would be larger than MAXREAL, the largest value representable.
 
Note
For n > 12, the algorithm used computes the value of Hn using a recursion from the values of H11 and H12. The computation time increases with n-11 and the computation accuracy decreases with n-11.
