NAME
Math::GSL - Perl interface to the GNU Scientific Library (GSL)
VERSION
Version 0.43
SYNOPSIS
use Math::GSL::Matrix; my $matrix = Math::GSL::Matrix->new(5,5); # 5x5 zero matrix # note that columns and rows are zero-based $matrix->set_col(0, [1..5]) # set *first* column to 1,2,3,4,5 ->set_row(2, [5..9]); # set *third* column to 5,6,7,8,9 my @matrix = $matrix->as_list; # matrix as Perl list my $gsl_matrix = $matrix->raw; # underlying GSL object use Math::GSL::RNG; my $rng = Math::GSL::RNG->new; my @random_numbers = $rng->get(1000); use Math::GSL::Deriv qw/:all/; my $function = sub { my $x=shift; sin($x**2) }; my ($status,$val,$err) = gsl_deriv_central($function, 5, 0.01 ); use Math::GSL qw/gsl_version/; # get a version object for the version of the underlying GSL library, # which will stringify to a version number my $gsl_version = gsl_version(); Each GSL subsystem has its own module. For example, the random number generator subsystem is Math::GSL::RNG. Many subsystems have a more Perlish and object-oriented frontend which can be used, as the above example shows. The raw GSL object is useful for using the low- level GSL functions, which in the case of the Matrix subsystem, would be of the form gsl_matrix_* . Each module has further documentation about the low-level C functions as well as using the more intuitive (but slightly slower) object-oriented interface.

COMPILING ISSUES
Some operating system configurations will make the compilation of Math::GSL fail. One common problem that happens on RedHat Linux (RHEL) and CentOS looks like this: Error: Can't load '/usr/src/misc/perl-package/Math-GSL-0.20/blib/arch/auto/Math/GSL/Errno/Errno.so' for module Math::GSL::Errno: /usr/src/misc/perl-package/Math-GSL-0.20/blib/arch/auto/Math/GSL/Errno/Errno.so: cannot restore segment prot after reloc: Permission denied at /usr/lib/perl5/5.10.0/i386-linux-thread-multi/DynaLoader.pm line 203. # at blib/lib/Math/GSL/Errno.pm line 10 This is due the the SE Linux setting being set to "enforcing". To Temporarily disable enforcement on a running system: /usr/sbin/setenforce 0 To permanently disable enforcement during a system startup change "enforcing" to "disabled" in ''/etc/selinux/config'' and reboot.
