       This is an interface to the Special Function package present in the GNU Scientific Library.  Please note
       that:

       Complete Fermi-Dirac Integrals:

        F_j(x)   := 1/Gamma[j+1] Integral[ t^j /(Exp[t-x] + 1), {t,0,Infinity}]

       Incomplete Fermi-Dirac Integrals:

        F_j(x,b) := 1/Gamma[j+1] Integral[ t^j /(Exp[t-x] + 1), {t,b,Infinity}]

gsl_sf_fermi_dirac_int
         Signature: (double x(); double [o]y(); double [o]e(); int j)

       Complete integral F_j(x) for integer j

       gsl_sf_fermi_dirac_int does not process bad values.  It will set the bad-value flag of all output
       ndarrays if the flag is set for any of the input ndarrays.

   gsl_sf_fermi_dirac_mhalf
         Signature: (double x(); double [o]y(); double [o]e())

       Complete integral F_{-1/2}(x)

       gsl_sf_fermi_dirac_mhalf does not process bad values.  It will set the bad-value flag of all output
       ndarrays if the flag is set for any of the input ndarrays.

   gsl_sf_fermi_dirac_half
         Signature: (double x(); double [o]y(); double [o]e())

       Complete integral F_{1/2}(x)

       gsl_sf_fermi_dirac_half does not process bad values.  It will set the bad-value flag of all output
       ndarrays if the flag is set for any of the input ndarrays.

   gsl_sf_fermi_dirac_3half
         Signature: (double x(); double [o]y(); double [o]e())

       Complete integral F_{3/2}(x)

       gsl_sf_fermi_dirac_3half does not process bad values.  It will set the bad-value flag of all output
       ndarrays if the flag is set for any of the input ndarrays.

   gsl_sf_fermi_dirac_inc_0
         Signature: (double x(); double [o]y(); double [o]e(); double b)

       Incomplete integral F_0(x,b) = ln(1 + e^(b-x)) - (b-x)

       gsl_sf_fermi_dirac_inc_0 does not process bad values.  It will set the bad-value flag of all output
       ndarrays if the flag is set for any of the input ndarrays.
