BESSELI

Formulas / BESSELI
Compute the modified Bessel function.
BESSELI(x,n)
  • x - The value to evaluate the function on
  • n - The order of the Bessel function

Examples

  • =BESSELI(1.5, 1)

    The BESSELI function is used to calculate the modified Bessel function of the first kind. It takes two arguments: the x value and the order. For example, the formula calculates the modified Bessel function of 1.5 with an order of 1.

Summary

The BESSELI function calculates a modified Bessel function with purely imaginary arguments. It returns errors if either x or n is not a number, or if n is negative.

  • The BESSELI function calculates a modified Bessel function with imaginary arguments.
  • The BESSELI function returns a #VALUE! error if either x or n are not numeric.
  • The BESSELI function cannot calculate the n-th modified Bessel function if n is less than 0.


Frequently Asked Questions

What is the BESSELI function?
The BESSELI function is used to calculate the modified Bessel function of a variable. The modified Bessel function is the same as the Bessel function with imaginary arguments.
What happens if the arguments are not numerical?
If the arguments are not numerical, the BESSELI function will return a #VALUE! error.
What happens if the n argument is negative?
If the n argument is negative, the BESSELI function will return a #NUM! error.
