BESSELK

Returns the modified Bessel function Kn(x).

Sample Usage

BESSELK(2.5,1)
BESSELK(C5,C6)

Syntax

BESSELK(x,n)

  • x - The value on which the function will be calculated.
  • n - The order of the Bessel function.

Examples

BESSELK(2.5,1) returns the modified Bessel function at 2.5 with an order of 1.
BESSELK(C5,C6) returns the modified Bessel function, according to the arguments specified in cells C5 and C6.

Notes

  • If n is not an integer, it is truncated.
  • If n < 0, BESSELK returns an error. 
  • If n is nonnumeric, BESSELK returns an error.
