Regular Bessel Function - Fractional Order

Function: double gsl_sf_bessel_Jnu (double nu, double x)
Function: int gsl_sf_bessel_Jnu_e (double nu, double x, gsl_sf_result * result)
These routines compute the regular cylindrical Bessel function of fractional order @math{nu}, @math{J_\nu(x)}.

Function: int gsl_sf_bessel_sequence_Jnu_e (double nu, gsl_mode_t mode, size_t size, double v[])
This function computes the regular cylindrical Bessel function of fractional order @math{\nu}, @math{J_\nu(x)}, evaluated at a series of @math{x} values. The array v of length size contains the @math{x} values. They are assumed to be strictly ordered and positive. The array is over-written with the values of @math{J_\nu(x_i)}.
