Regular Cylindrical Bessel Functions
- Function: double gsl_sf_bessel_J0 (double x)
-
- Function: int gsl_sf_bessel_J0_e (double x, gsl_sf_result * result)
-
These routines compute the regular cylindrical Bessel function of zeroth
order, J_0(x).
- Function: double gsl_sf_bessel_J1 (double x)
-
- Function: int gsl_sf_bessel_J1_e (double x, gsl_sf_result * result)
-
These routines compute the regular cylindrical Bessel function of first
order, J_1(x).
- Function: double gsl_sf_bessel_Jn (int n, double x)
-
- Function: int gsl_sf_bessel_Jn_e (int n, double x, gsl_sf_result * result)
-
These routines compute the regular cylindrical Bessel function of
order n, J_n(x).
- Function: int gsl_sf_bessel_Jn_array (int nmin, int nmax, double x, double result_array[])
-
This routine computes the values of the regular cylindrical Bessel
functions J_n(x) for n from nmin to nmax
inclusive, storing the results in the array result_array. The
values are computed using recurrence relations, for efficiency, and
therefore may differ slightly from the exact values.
