man PDL::GSLSF::EXP () - PDL interface to GSL Special Functions
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.
SYNOPSIS
Functions
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 piddles if the flag is set for any of the input piddles.
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 piddles if the flag is set for any of the input piddles.
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 piddles if the flag is set for any of the input piddles.
