Returns the Bessel function of the second kind at x for the specified order. The Bessel functions of the second kind are defined as the solutions to the Bessel differential equation

Bessel differential equation

which are singular at the origin.

The n-th order Bessel function of x is:

n-th order Bessel function

where J denotes the Bessel function of the first kind.

The plot below shows the Bessel function for n=0,1,2,3,4,5.

BESSELY function

Order must be greater than or equal to 0. If order is not an integer, it is truncated. X must be greater than or equal to 0. For more information on the Bessel function see the reference at MathWorld.
