Usage                INTEGER N
REAL X,Y
Y=FNS_yh1(N,X)
 
Description                
FNS_yhn returns the value of the spherical Bessel function of the second kind and order n+½ of x, yn+½(x). Yn+½(x) is defined for all values of n and for all positive values of x.
 
Errors                
FNS_yhn 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.

yn+½(x)
Note
       
The algorithm used computes the value of yn+½ using a recursion from the values of y½ and y1½. The computation time increases with n and the computation accuracy decreases with n.
