FNYhnreturns the value of the cylindrical Bessel function of the second kind and ordern+½ ofx,Yn+½(x).Yn+½(x) is defined for all values ofnand for all positive values ofx.
Errors
FNYhncauses an HTBasic error if its arguments are not of the types shown in the USAGE section, above, or ifxis negative or zero.

Note
The algorithm used computes the value ofYn+½ using a recursion from the values ofY½ andY1½. The computation time increases withnand the computation accuracy decreases withn.
