NAME

6       PDL::GSLSF::EXP - PDL interface to GSL Special Functions
7

DESCRIPTION

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

SYNOPSIS

FUNCTIONS

14   gsl_sf_exp
15         Signature: (double x(); double [o]y(); double [o]e())
16
17       Exponential
18
19       gsl_sf_exp does not process bad values.  It will set the bad-value flag
20       of all output piddles if the flag is set for any of the input piddles.
21
22   gsl_sf_exprel_n
23         Signature: (double x(); double [o]y(); double [o]e(); int n)
24
25       N-relative Exponential. exprel_N(x) = N!/x^N (exp(x) - Sum[x^k/k!,
26       {k,0,N-1}]) = 1 + x/(N+1) + x^2/((N+1)(N+2)) + ... = 1F1(1,1+N,x)
27
28       gsl_sf_exprel_n does not process bad values.  It will set the bad-value
29       flag of all output piddles if the flag is set for any of the input
30       piddles.
31
32   gsl_sf_exp_err
33         Signature: (double x(); double dx(); double [o]y(); double [o]e())
34
35       Exponential of a quantity with given error.
36
37       gsl_sf_exp_err does not process bad values.  It will set the bad-value
38       flag of all output piddles if the flag is set for any of the input
39       piddles.
