- Function: int gsl_sf_bessel_I0_e (double x, gsl_sf_result * result)

- Function: int gsl_sf_bessel_I1_e (double x, gsl_sf_result * result)
-
These routines compute the regular modified cylindrical Bessel function
of first order, @math{I_1(x)}.
- Function: double gsl_sf_bessel_In (int n, double x)

- Function: int gsl_sf_bessel_In_e (int n, double x, gsl_sf_result * result)

- Function: int gsl_sf_bessel_In_array (int nmin, int nmax, double x, double result_array[])
-
This routine computes the values of the regular modified cylindrical
Bessel functions @math{I_n(x)} for @math{n} from nmin to
nmax inclusive, storing the results in the array
result_array. The start of the range nmin must be positive
or zero. The values are computed using recurrence relations, for
efficiency, and therefore may differ slightly from the exact values.
