BESSELJ

Syntax:

BESSELJ ( x , n )

Description: The Bessel function Jn(x).

Mathematical Formula:

The n-th order Bessel function of the variable x is:

where:

is the Gamma function.

Arguments:

Name	Type	Description
x	number	The value at which to evaluate the function.
n	number	The order of the Bessel function. This value is truncated to an integer.

 

Return Type and Value: number – The Bessel function Jn(x).

However, if n < 0, #NUM! is returned.

[Example:

BESSELJ(-5.6,0) results in 0.026970887
BESSELJ(2.345,5) results in 0.014627862
