NAME

Math::GSL - Perl interface to the GNU Scientific Library (GSL)

VERSION

Version 0.49

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.
