Returns the modified Bessel function, which is equivalent to the Bessel function evaluated for purely imaginary arguments.
The BESSELI function syntax has the following arguments:
X Required. The value at which to evaluate the function.
N Required. The order of the Bessel function. If n is not an integer, it is truncated.
If x is nonnumeric, BESSELI returns the #VALUE! error value.
If n is nonnumeric, BESSELI returns the #VALUE! error value.
If n < 0, BESSELI returns the #NUM! error value.
The n-th order modified Bessel function of the variable x is:
In order to use the BESSELI formula, start with your edited Excellentable:
Then type in the BESSELI formula in the area you would like to display the outcome:
By adding the values you would like to calculate the BESSELI formula for, Excellentable will generate the outcome:
