NAME

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

DESCRIPTION

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

FUNCTIONS

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

       Exponential

       gsl_sf_exp 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_exprel_n
         Signature: (double x(); double [o]y(); double [o]e(); int n)

       N-relative Exponential. exprel_N(x) = N!/x^N (exp(x) - Sum[x^k/k!, {k,0,N-1}]) = 1 +
       x/(N+1) + x^2/((N+1)(N+2)) + ... = 1F1(1,1+N,x)

       gsl_sf_exprel_n 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_exp_err
         Signature: (double x(); double dx(); double [o]y(); double [o]e())

       Exponential of a quantity with given error.

       gsl_sf_exp_err 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.
