Bessel function I for real numbers

Calculator for calculating the modified Bessel function Iv(z) of the first kind

Bessel function Iv (z) of the first kind


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

This function expects real numbers as arguments. Bessel functions for complex numbers can be found here.

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

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

The result is a complex number if z is negative and n is a decimal number.
