BESSELI function

The BESSELI function is one of the engineering functions. It is used to return the modified Bessel function, which is equivalent to the Bessel function evaluated for purely imaginary arguments.

Syntax

BESSELI(x, n)

The BESSELI function has the following arguments:

Argument	Description
x	The value at which to evaluate the function.
n	The order of the Bessel function, a numeric value greater than or equal to 0.
