Irregular Cylindrical Bessel Functions

Function: double gsl_sf_bessel_Y0 (double x)

Function: int gsl_sf_bessel_Y0_e (double x, gsl_sf_result * result)

These routines compute the irregular cylindrical Bessel function of zeroth order, @math{Y_0(x)}, for @math{x>0}.

Function: double gsl_sf_bessel_Y1 (double x)

Function: int gsl_sf_bessel_Y1_e (double x, gsl_sf_result * result)

These routines compute the irregular cylindrical Bessel function of first order, @math{Y_1(x)}, for @math{x>0}.

Function: double gsl_sf_bessel_Yn (int n,double x)

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

These routines compute the irregular cylindrical Bessel function of order n, @math{Y_n(x)}, for @math{x>0}.

Function: int gsl_sf_bessel_Yn_array (int nmin, int nmax, double x, double result_array[])

This routine computes the values of the irregular cylindrical Bessel functions @math{Y_n(x)} for @math{n} from nmin to nmax inclusive, storing the results in the array result_array. The domain of the function is @math{x>0}. The values are computed using recurrence relations, for efficiency, and therefore may differ slightly from the exact values.
