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.

BUGS
This software is still in active development, we appreciate your detailed bug reports and
documentation patches. Please report any bugs or feature requests to the authors directly.
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 to 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.
