Bessel-I function for complex numbers

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