Usage                INTEGER N
REAL X,Y
Y=FNS_khn(N,X)
 
Description                
FNS_khn returns the value of the modified spherical Bessel function of the third kind and order n+½ of x, kn+½(x). Kn+½(x) is defined for all values of n and for all positive values of x.
 
Errors                
FNS_khn 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 kn+½ using a recursion from the values of k½ and k1½. The computation time increases with n and the computation accuracy decreases with n.
