Algorithm for Computing the Modified Bessel Function of the First Kind

For the modified Bessel function of the first kind of order v, also known as the hyperbolic Bessel function of the first kind, lv(x) is a solution of the following differential equation.

x 2 d 2 w d x 2 + x d w d x ( x 2 + v 2 ) w = 0

The function is defined according to the following intervals for the input values.

v x
v \ x [ 0 , )

This node supports the entire domain of this function that produces real-valued results. For any integer value of order v, the function is defined for all real values of x. For any noninteger value of order v, the function is defined for nonnegative real values of x.

Desktop OS: Windows

FPGA: Not supported
