double SphBessel1st (int n, double x);
Computes the spherical Bessel function of the first kind of order n, which is a solution to the following differential equation:
The following equation shows the relationship of the spherical Bessel function of the first kind to the Bessel function of the first kind.
For any integer value of order n, the function is defined for nonnegative real values of x.
