🎀 lapacke_cgbtrs.c — a LAPACK girlie deep dive 🎀

okay so bestie, this page is from LAPACK (yes, that LAPACK 💅) and it's basically the glow-up doc for one single function: LAPACKE_cgbtrs. That's it. That's the whole page. She's short, she's iconic, and we're gonna read her together 🫶

---

✨ NAME ✨

lapacke_cgbtrs.c — literally just the file name, no cap. That's the whole NAME section, she said "I am my file" 💀

---

🌸 SYNOPSIS 🌸

#include 'lapacke_utils.h'

not me including the header with the single quotes exactly as written 😭 copy it verbatim bestie, don't get cute and swap in angle brackets, that's not what the page says.

🦋 Functions 🦋

here's the one and only star of the show, the main character herself:

lapack_int LAPACKE_cgbtrs (int matrix_layout, char trans, lapack_int n,
    lapack_int kl, lapack_int ku, lapack_int nrhs, const
    lapack_complex_float *ab, lapack_int ldab, const lapack_int *ipiv,
    lapack_complex_float *b, lapack_int ldb)

look at all those parameters, she ate 🔥 and yes, ab and b are const-less vs const differently — ab is a const lapack_complex_float * while b is a plain lapack_complex_float *. Do not touch that. Periodt.

👑 Function Documentation 👑

💖 lapack_int LAPACKE_cgbtrs (int matrix_layout, char trans, lapack_int n, lapack_int kl, lapack_int ku, lapack_int nrhs, const lapack_complex_float * ab, lapack_int ldab, const lapack_int * ipiv, lapack_complex_float * b, lapack_int ldb) 💖

so this is the exact same signature as up top, just formatted all official and doc-y ✨ (they wrote * ab with a space before ab here — yes, we're keeping it, don't @ me 💅).

the vibe check: Definition at line 36 of file lapacke_cgbtrs.c. that's your source of truth, that's where she lives 🏡

lowkey the page doesn't explain what the parameters do — it just hands you the signature and dips 🙈 so ngl bestie, this is all the docs you're getting from this page. no invented lore, we don't do that here 🧚
