👑 eye — identity matrix & preconditionner, but make it ✨do nothing✨

okay bestie so this is from the rheolef manual, section 5 (iykyk), and it's literally just about eye. yes, like your eyeballs. no, not really. sit down, I got you 💖

🌸 NAME 🌸

eye — the identity matrix and preconditionner, straight outta rheolef-7.2 🫶

🦋 DESCRIPTION 🦋

so following, like, octave's whole vibe, eye means the identity matrix. periodt. 💅

but here's the twist — in this house, eye() is a function call that hands you back the identity preconditionner, all dressed up as a solver(4). it's giving glow-up fr fr.

and the dimensions of eye()? not specified anywhere, babe — they're determined by the context. main character energy: it just knows. ✨

this class is lowkey iconic in the context of preconditionner interfaces, because it lets you specify a do-nothing preconditionner. yes, you heard me right: a preconditionner that does absolutely nothing. it's the "no thoughts, head empty" of linear algebra 😭 and honestly? slay.

see like cg(5) for an example if you wanna see it in the wild 💜

🎀 IMPLEMENTATION 🎀

ngl this documentation was generated from the file linalg/lib/eye.h — that's the receipt, keep it 🧾

okay that's the whole page, no cap 🍓

this was rheolef, Version 7.2 — that's the source and the version, mwah 💋 — and yes it's the eye(5rheolef) page, section 5, exactly as the footer says. bye bestie, go write a do-nothing preconditionner, I believe in you 🧚💜
