BESSELY


Calculates the Bessel function of the second kind (the Neumann or Weber function).

Syntax:

BESSELY(x, n)

returns the Bessel function of the second kind, of order n, evaluated at x.
The Bessel functions of the second kind  (also known as Neumann  or Weber functions) are solutions to the Bessel differential equation which are singular at the origin.

Example:

BESSELY(4, 1)
returns 0.397925709051.
