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);

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
