Description

Returns a modified Bessel function, which is equivalent to Bessel functions calculated for purely imaginary arguments.

Syntax

BESSELK (X; N)

The syntax of the BESSELK function has the following arguments:

X. - required argument. The value for which the function is calculated.

n is a required argument. The order of the Bessel function. If n is not an integer, it is reduced.

Notes

If x is not a numeric value, the BESSELK function returns #VALUE! .

If n is not a numeric value, the BESSELK function returns #VALUE! .

If n <0, the BESSELK function returns #NUM! .

The modified Bessel function of the nth order for the variable x looks like this:

where Jn and Yn are Bessel functions J and Y, respectively.
