1-D Minimization

NAME

Math::GSL::Min - 1-D Minimization

SYNOPSIS

    use Math::GSL::Min qw/:all/;
    use Math::GSL::Const qw/$M_PI/;
    my $m = gsl_min_fminimizer_alloc($gsl_min_fminimizer_goldensection);
    gsl_min_fminimizer_set_with_values($m,
        sub { cos($_[0]) },
        3, cos(3),
        0, cos(0),
        2*$M_PI, cos(2*$M_PI)
    );
    my $status  = gsl_min_fminimizer_iterate($m);
    my $x_min   = gsl_min_fminimizer_x_minimum($m);
    my $x_lower = gsl_min_fminimizer_x_lower($m);
    my $x_upper = gsl_min_fminimizer_x_upper($m);
    my $f_min   = gsl_min_fminimizer_f_minimum($m);
    my $f_lower = gsl_min_fminimizer_f_lower($m);
    my $f_upper = gsl_min_fminimizer_f_upper($m);

DESCRIPTION

Here is a list of all the functions in this module :

•

gsl_min_fminimizer_alloc($type)

•

"gsl_min_fminimizer_free"

Don't call this function explicitly. It will be called automatically in DESTROY for fminimizer.

•

"gsl_min_fminimizer_set "

Don't apply this function twice to the same fminimizer. It will cause a memory leak. Instead of this you should create new fminimizer.

•

"gsl_min_fminimizer_set_with_values"

Don't apply this function twice to the same fminimizer. It will cause a memory leak. Instead of this you should create new fminimizer.

•

gsl_min_fminimizer_iterate($m)

•

"gsl_min_fminimizer_name "

•

gsl_min_fminimizer_x_minimum($m)

•

gsl_min_fminimizer_x_lower($m)

•

gsl_min_fminimizer_x_upper($m)

•

gsl_min_fminimizer_f_minimum($m)

•

gsl_min_fminimizer_f_lower($m)

•

gsl_min_fminimizer_f_upper($m)

•

gsl_min_fminimizer_minimum($m)

•

gsl_min_test_interval($m)

•

gsl_min_find_bracket($m)

This module also includes the following constants :

•

$gsl_min_fminimizer_brent

•

$gsl_min_fminimizer_goldensection
