Loadable Function: z = gsl_sf_bessel_Jn (arg1, arg2)
Loadable Function: [z, err] = gsl_sf_bessel_Jn (…)

Computes the regular cylindrical Bessel function of order n, J_n(x).

err contains an estimate of the absolute error in the value z.

This function is from the GNU Scientific Library, see http://www.gnu.org/software/gsl/ for documentation.
