posv_comp_grp(3)

okay so bestie 💖 you're reading posv_comp_grp(3) from the Library Functions Manual, and this page is the Cholesky computational-routines group — factor, cond, etc. — like a whole little menu of LAPACK helpers. Let's go 💅✨

🌸 NAME 🌸

posv_comp_grp — Cholesky: computational routines (factor, cond, etc.). That's the whole vibe, bestie: it's the Cholesky computational-routines group, and it's giving factor, cond, etc. energy 🎀.

🦋 SYNOPSIS 🦋

✨ Topics ✨

okay so the topics are split into storage-style groups, and every single routine is listed below. No skipping, no cap 🫶.

• pocon — condition number estimate, coming through 💅
• potrf — triangular factor, the classic.
• potrf2 — triangular factor panel, recursive? — yes, the question mark is literally canon, bestie 😭
• potf2 — triangular factor panel, level 2.
• pstrf — triangular factor, with pivoting — main-character pivot energy.
• pstf2 — triangular factor, with pivoting panel, level 2.
• potrs — triangular solve using factor.

💀 Detailed Description 💀

bestie, this section is literally empty in the source. There are no extra details here — it's giving "section exists, content said bye" 🙈. No cap, we're moving on.

okay that's the whole page, bestie 🫶💖 This one comes from LAPACK, Version 3.12.0, and the page is posv_comp_grp(3) in the Library Functions Manual. Date check: there's literally no date printed in the footer, so I'm not making one up — no cap. Bye bestie, go slay some Cholesky 💅✨
