# Math::GSL::Min(3pm)

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`
