# Bessel-K function for complex numbers

Calculator for the modified Bessel function Kn (z) of the second type

## Bessel function Kn (z) of the second kind

The Bessel-K function calculates the modified Bessel function Kn (z) of the second kind. The modified Bessel functions do not show an oscillating but an exponential behavior. Bessel-K (n, z) is a solution of the modified Bessel differential equation.

This function expects a complex number as argument z . Bessel functions for real numbers can be found here.

To perform the calculation, enter the complex number and the order number. Then click on the 'Calculate' button.
