 | BESSELK function |
Returns the modified Bessel function Kn(x), which is equivalent to the Bessel functions evaluated for purely imaginary arguments.
Syntax
BESSELK(x,n)
Argument | Description | Remarks |
|---|---|---|
x | The value at which to evaluate the function. |
|
n | The order of the Bessel function. |
|
General remarks
The n-th order modified Bessel function of the variable x is as follows:
where Jn and Yn are the J and Y Bessel functions, respectively.
Example
To make the following example easier to understand, you can copy the data to a blank sheet and then enter the function underneath the data. Do not select the row or column headings (1, 2, 3... A, B, C...) when you copy the sample data to a blank sheet.
