Y=FNYn(N,X)
Description
FNYn returns the value of the cylindrical Bessel function of the second kind and order n of x, Yn(x). Yn(x) is defined for all positive values of x.
Errors
FNYn causes an HTBasic error if its argument is not of type REAL or if x is negative or zero.

Note
|
The algorithm used computes the value of Yn using a recursion from the values of Y0 and Y1. The computation time increases with n and the computation accuracy decreases with n - 1.
