Math::GSL::SF - Special Functions
use Math::GSL::SF qw /:all/;
This module contains a data structure named gsl_sf_result. To create a new one use $r = Math::GSL::SF::gsl_sf_result_struct->new; You can then access the elements of the structure in this way : $r->{val} or $r->{err}
Here is a list of all included functions:
gsl_sf_airy_Ai_e($x, $mode)
gsl_sf_airy_Ai($x, $mode, $result)
- These routines compute the Airy function Ai($x) with an accuracy specified by $mode. $mode should be $GSL_PREC_DOUBLE, $GSL_PREC_SINGLE or $GSL_PREC_APPROX. $result is a gsl_sf_result structure.
gsl_sf_airy_Bi_e($x, $mode, $result)
gsl_sf_airy_Bi($x, $mode)
- These routines compute the Airy function Bi($x) with an accuracy specified by $mode. $mode should be $GSL_PREC_DOUBLE, $GSL_PREC_SINGLE or $GSL_PREC_APPROX. $result is a gsl_sf_result structure.
gsl_sf_airy_Ai_scaled_e($x, $mode, $result)
gsl_sf_airy_Ai_scaled($x, $mode)
- These routines compute a scaled version of the Airy function S_A($x) Ai($x). For $x>0 the scaling factor S_A($x) is \exp(+(2/3) $x**(3/2)), and is 1 for $x<0.
gsl_sf_airy_Bi_scaled_e($x, $mode, $result)
gsl_sf_airy_Bi_scaled($x, $mode)
- These routines compute a scaled version of the Airy function S_B($x) Bi($x). For $x>0 the scaling factor S_B($x) is exp(-(2/3) $x**(3/2)), and is 1 for $x<0.

You can import the functions that you want to use by giving a space separated list to Math::GSL::SF when you use the package. You can also write use Math::GSL::SF qw/:all/ to use all avaible functions of the module. Note that the tag names begin with a colon. Other tags are also available, here is a complete list of all tags for this module :
airy
bessel
clausen
hydrogenic
coulumb
coupling
dawson
debye
dilog
factorial
misc
elliptic
error
hypergeometric
laguerre
legendre
gamma
transport
trig
zeta
eta
vars
For more informations on the functions, we refer you to the GSL offcial documentation: http://www.gnu.org/software/gsl/manual/html_node/ Tip : search on google: site:http://www.gnu.org/software/gsl/manual/html_node/name_of_the_function_you_want
This example computes the dilogarithm of 1/10 :
use Math::GSL::SF qw/dilog/; my $x = gsl_sf_dilog(0.1); print "gsl_sf_dilog(0.1) = $x\n";
An example using Math::GSL::SF and gnuplot is in the examples/sf folder of the source code.
