BESSELI Function

The BESSELI () is an engineering function which takes x, n as argument and returns the modified Bessel function which is equivalent to the Bessel function evaluated for purely imaginary arguments.

Formula:


=BESSELI(x,n)
In the above syntax, the argument x denotes the value at which the function is to be evaluated and n denotes the positive integer representing the order of the function.
