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