Calculation of the exponentially scaled modified Bessel function Kn (z) of the second kind
The Bessel-Ke function calculates the exponentially scaled modified Bessel function Kn (z) of the second kind. The modified Bessel functions do not show an oscillating but an exponential behavior. BesselKe (n, z) is a solution to the modified Bessel differential equation.
This function expects real numbers as arguments. You can find Bessel functions for complex numbers here .
To perform the calculation, enter a real number and the order number. Then click on the 'Calculate' button.

The Bessel-Ke function calculates the exponentially scaled modified Bessel function Kn (z) of the second kind. The modified Bessel functions do not show an oscillating but an exponential behavior. BesselKe (n, z) is a solution of the modified Bessel differential equation.
The result can be a complex number if z is negative and n is a decimal number.
