BESSELK
This function calculates the modified Bessel function of the second kind evaluated for purely imaginary arguments.
Syntax
BESSELK(value, order)
Arguments
This function has these arguments:
Argument | Description |
|---|---|
value | Value at which to evaluate the function |
order | Number representing the order of the function; if it is not an integer, it is truncated |
Remarks
This function is also called the Neumann function. If the value or order is non-numeric then a #Value! error is returned. If the order is less than 0 then the #NUM! error is returned.
Data Types
Accepts numeric data for both arguments. Returns numeric data.
Examples
BESSELK(A4,D5)
BESSELK(R4C1,R5C4)
BESSELK(1.85,2) gives the result 0.32165379
