Usage INTEGER N
REAL X,Y
Y=FNYhn(N,X)
Description
FNYhn returns the value of the cylindrical 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
FNYhn 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)
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.
