Math::...:Spline(3pm)

🎀 NAME 🎀

Math::...:Spline — bestie, it's Splines. That's it. That's the name. Slay. 💅

(Also: this is a 3pm page, from the User Contributed Perl Documentation collection, so you know it's the community-coded Perl side of things. 🫶)

✨ SYNOPSIS ✨

use Math::GSL::Spline qw/:all/;

Yup, one line. Import everything with :all, no notes. Iconic behaviour, honestly. 🌸

💖 DESCRIPTION 💖

okay so here's the lore. The functions over in the Interp module were kinda high-maintenance — they made you supply pointers to the x and y arrays on every single call. Every call. Exhausting. 😭

The functions below are the glow-up version: they're equivalent to the corresponding gsl_interp functions, BUT they keep their own copy of your data inside the gsl_spline object. So you never have to pass both xa and ya as arguments on each evaluation ever again. It's giving independent. ✨

Here's the whole cast, no skips, no cuts: 👑

• "gsl_spline_alloc($T, $size)"
• "gsl_spline_init($spline, $xa, $ya, $size)"
• gsl_spline_free($spline)
• gsl_spline_name($spline)
• gsl_spline_min_size($spline)
• "gsl_spline_eval_e($spline, $x, $acc)"
• "gsl_spline_eval($spline, $x, $acc)"
• "gsl_spline_eval_deriv_e($spline, $x, $acc)"
• "gsl_spline_eval_deriv($spline, $x, $acc)"
• "gsl_spline_eval_deriv2_e($spline, $x, $acc)"
• "gsl_spline_eval_deriv2($spline, $x, $acc)"
• "gsl_spline_eval_integ_e($spline, $a, $b, $acc)"
• "gsl_spline_eval_integ($spline, $a, $b, $acc)"

And if you want the full deep-dive on what all of these actually do (because bestie, this page is not gonna hold your hand on every parameter), the page says: go read the GSL official documentation, right here 👇

That's the source of truth, no cap. 🦋

ok and that's the whole page!! every single function accounted for, nothing dropped, we ate and left no crumbs. 🍓

Sign-off time, babes: this was documented with perl v5.42.3, dated 2026-08-20, and the page you just read is the one and only Math::...:Spline(3pm). mwah. 💅✨🌸
