double ModBessel2nd (int n, double x);
Computes the modified Bessel function Kr = K(r,x) of the second kind of integer order r. The modified Bessel function of the second kind of order r is defined as follows:
which is a solution of the following differential equation:
For any integer value of order n, the function is defined for nonnegative real values of x.
