S_hh2n
Spherical Hankel function of the second kind, order n+½.
 
Loading        LOADSUB ALL FROM "BESRC.HTS"
or LOADSUB FROM "MATHLIB.HTS"
 
Usage                INTEGER N
REAL X
COMPLEX C
C=FNS_hh2n(N,X)
 
Description                
FNS_hh2n returns the value of the spherical Hankel function of the second kind and order n+½ of x, hn+½(2)(x). Hn+½(2)(x) is defined for all values of n and for all positive values of x.
 
Errors                
FNS_hh2n causes an HTBasic error if its arguments are not of the types shown in the USAGE section, above, or if x is negative or zero.

Note
The algorithm used computes the value of hn+½(2) using a recursion from the values of h½(2) and h1½(2). The computation time increases with n and the computation accuracy decreases with n.
