Module Version: 0.13_03   Source   Latest Release: Math-GSL-0.20

NAME ^

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

VERSION ^

Version 0.13_03

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 = map { $rng->get } (1 .. 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 );

Each GSL subsystem has it's 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 subsytem, 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.

DEVELOPMENT ^

If you would like the help develop Math::GSL, email the authors and do

    git clone http://leto.net/code/Math-GSL.git 
    cd Math-GSL
    git checkout -b bleed   # create new local branch
    git pull origin bleed   # pull in remote bleed
