NAME

       PDL::GSLSF::ELLINT - PDL interface to GSL Special Functions

DESCRIPTION

       This is an interface to the Special Function package present in the GNU Scientific Library.

SYNOPSIS

FUNCTIONS

   gsl_sf_ellint_Kcomp
	 Signature: (double k(); double [o]y(); double [o]e())

       Legendre form of complete elliptic integrals K(k) = Integral[1/Sqrt[1 - k^2 Sin[t]^2], {t, 0, Pi/2}].

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

   gsl_sf_ellint_Ecomp
	 Signature: (double k(); double [o]y(); double [o]e())

       Legendre form of complete elliptic integrals E(k) = Integral[  Sqrt[1 - k^2 Sin[t]^2], {t, 0, Pi/2}]

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

   gsl_sf_ellint_F
	 Signature: (double phi(); double k(); double [o]y(); double [o]e())

       Legendre form of incomplete elliptic integrals F(phi,k)	 = Integral[1/Sqrt[1 - k^2 Sin[t]^2], {t, 0, phi}]

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

   gsl_sf_ellint_E
	 Signature: (double phi(); double k(); double [o]y(); double [o]e())

       Legendre form of incomplete elliptic integrals E(phi,k)	 = Integral[  Sqrt[1 - k^2 Sin[t]^2], {t, 0, phi}]

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

   gsl_sf_ellint_P
	 Signature: (double phi(); double k(); double n();
		     double [o]y(); double [o]e())

       Legendre form of incomplete elliptic integrals P(phi,k,n) = Integral[(1 + n Sin[t]^2)^(-1)/Sqrt[1 - k^2 Sin[t]^2], {t, 0, phi}]

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

   gsl_sf_ellint_D
	 Signature: (double phi(); double k(); double n();
		     double [o]y(); double [o]e())

       Legendre form of incomplete elliptic integrals D(phi,k,n)

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

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

       Carlsons symmetric basis of functions RC(x,y)   = 1/2 Integral[(t+x)^(-1/2) (t+y)^(-1)], {t,0,Inf}

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

   gsl_sf_ellint_RD
	 Signature: (double x(); double yy(); double z(); double [o]y(); double [o]e())

       Carlsons symmetric basis of functions RD(x,y,z) = 3/2 Integral[(t+x)^(-1/2) (t+y)^(-1/2) (t+z)^(-3/2), {t,0,Inf}]

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

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

   gsl_sf_ellint_RJ
	 Signature: (double x(); double yy(); double z(); double p(); double [o]y(); double [o]e())

       Carlsons symmetric basis of functions RJ(x,y,z,p) = 3/2 Integral[(t+x)^(-1/2) (t+y)^(-1/2) (t+z)^(-1/2) (t+p)^(-1), {t,0,Inf}]

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