Math::GSL::Min(3pm)

💖 Math::GSL::Min — bestie edition 💖

okay so this is the Math::GSL::Min page from the User Contributed Perl Documentation, and it's literally all about 1-D Minimization — like, finding the lowest point of a function in one dimension. obsessed. 🎀

✨ NAME ✨

Math::GSL::Min — 1-D Minimization. that's it, that's the whole name, she's simple and she slays 💅

---

🌸 SYNOPSIS 🌸

here's the whole vibe, copy it exactly or the compiler will come for you:

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);

like yes bestie, alloc her, set her, iterate her, then aggressively interrogate her about where the minimum is. main character energy fr fr. 👑

🦋 DESCRIPTION 🦋

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

• gsl_min_fminimizer_alloc($type) — makes you a brand new fminimizer, type and everything ✨
• gsl_min_fminimizer_free

not me calling this one myself — don't do it bestie!! 💀 this gets called automatically in DESTROY for fminimizer. it handles itself, she's independent.

• gsl_min_fminimizer_set

okay this is the important one: don't apply this function twice to the same fminimizer. it will cause a memory leak 😭 instead of doing that, you should create a new fminimizer. fresh start, new you, periodt.

• gsl_min_fminimizer_set_with_values

same warning, same energy: don't apply this function twice to the same fminimizer, it will cause a memory leak 🫠 instead of this you should create new fminimizer. don't be lazy, bestie.

• gsl_min_fminimizer_iterate($m) — the do-the-work one 🔥
• gsl_min_fminimizer_name
• gsl_min_fminimizer_x_minimum($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 💛

For more information on the functions, we refer you to the GSL official documentation: http://www.gnu.org/software/gsl/manual/html_node/ — go read it, it's giving reference material, iykyk 📚
