Linear(3pm)

💖 Linear(3pm) — the group chat rundown 💖

okay bestie, so this is a Perl manual page, and it lives in the User Contributed Perl Documentation section. We're talking about PDL::Filter::Linear today. Sit down, hydrate, let's go 🫶

---

✨ NAME ✨

PDL::Filter::Linear — linear filtering for PDL. literally that's the whole vibe 💅

---

🌈 SYNOPSIS 🌈

no cap, this is all you need to look at first:

$x = PDL::Filter::Linear->new(
        {Weights => $v,
         Point => 10});

$y = PDL::Filter::Gaussian->new(15,2); # 15 points, 2 std devn.

($pred,$corrslic) = $x->predict($dat);

like. she's giving "make a filter, then predict". iconic ✨

🦋 DESCRIPTION 🦋

So what is this actually? It's a wrapper for generic linear filters. Just for convenience — that's the whole point, bestie, it's not here to be deep, it's here to save you typing 😌

This should, in the future, use DataPresenter. (future plans, not current facts, okay? don't come for me 👀)

Also — and this is highkey the tea — this class should at some point learn to do FFT whenever it is useful. Right now: no. Someday: maybe. Periodt 💀

lowkey a tiny module, but she's got aspirations 🌸

🎀 sign-off 🎀

and that's the whole page, fr fr. it's from perl v5.42.3, dated 2026-08-19, and yes, my love, the header and footer both said Linear(3pm) because that's how manpages do — consistent queen 👑

goodbye, go filter something linear 💜
