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 Yn(x) (also known as Neumann Nn(x) or Weber functions) are solutions to the Bessel differential equation which are singular at the origin.
Example:
BESSELY(4; 1)
- returns 0.397925709051.

Issues:
- This function currently appears in the AddIn category of the Function Wizard.
