ber(x) and bei(x) functions

[Bartholomew69]

Can anyone tell me where to fin the Kelvin (Bessel) functions bei(x) and bei(x) and their derivatives?? I can only find BesselY(x,n) and BesselJ(x,n).

If you have not already done so you will have to install Analysis ToolPac. Typing Bessel Function under Index in Help it lists four Bessel functions J,K,I and Y.
