lapacke_zggsvp3.c(3)

💅 lapacke_zggsvp3.c — the manual page, but make it make sense

okay so bestie, before we even start: the manual name is lapacke_zggsvp3.c, and this whole page is LAPACK's auto-generated docs for exactly one function. that's it. that's the whole vibe. it's giving "reference card, not a tutorial" and honestly? iconic.

✨ NAME ✨

lapacke_zggsvp3.c — no cap, the name is just the filename. the C file is the moment. 🎀

---

🌸 SYNOPSIS 🌸

first things first, you gotta pull in the header:

#include 'lapacke_utils.h'

(yes, with the single quotes exactly like that — I'm not touching it, that's what the page says, periodt.)

🦋 Functions 🦋

one single function lives here, and she's a long one, so let me lay her out with full main-character energy:

lapack_int LAPACKE_zggsvp3 (int matrix_layout, char jobu, char jobv,
    char jobq, lapack_int m, lapack_int p, lapack_int n,
    lapack_complex_double *a, lapack_int lda, lapack_complex_double *b,
    lapack_int ldb, double tola, double tolb, lapack_int *k, lapack_int
    *l, lapack_complex_double *u, lapack_int ldu, lapack_complex_double
    *v, lapack_int ldv, lapack_complex_double *q, lapack_int ldq)

that's twenty whole arguments, bestie. twenty. she's high-maintenance and we respect her for it. 💀

👑 Function Documentation 👑

💖 lapack_int LAPACKE_zggsvp3 (...)

here she is again, spelled out in full, same signature, same everything — I'm not summarising, I'm not merging, I'm not "cleaning it up" because that's how you break a build and we do not break builds in this house:

lapack_int LAPACKE_zggsvp3 (int matrix_layout, char jobu, char jobv, char
    jobq, lapack_int m, lapack_int p, lapack_int n, lapack_complex_double *
    a, lapack_int lda, lapack_complex_double * b, lapack_int ldb, double
    tola, double tolb, lapack_int * k, lapack_int * l, lapack_complex_double
    * u, lapack_int ldu, lapack_complex_double * v, lapack_int ldv,
    lapack_complex_double * q, lapack_int ldq)

so what are all these cuties? quickly, in order, zero guessing on my part — the page gives us the types and the names and that's literally it:

• int matrix_layout — an int. it's the layout flag, first in line, doing her thing.
• char jobu — a char named jobu.
• char jobv — a char named jobv.
• char jobq — a char named jobq.
• lapack_int m — a lapack_int, obvs.
• lapack_int p — another one.
• lapack_int n — and the third of the trio.
• lapack_complex_double *a — pointer to your a, with lapack_int lda riding shotgun.
• lapack_complex_double *b — pointer to your b, with lapack_int ldb right behind.
• double tola — a plain double, named tola.
• double tolb — a plain double, named tolb.
• lapack_int *k — a pointer, so something's getting written back here 👀.
• lapack_int *l — same deal, pointer queen.
• lapack_complex_double *u — pointer to u, plus lapack_int ldu.
• lapack_complex_double *v — pointer to v, plus lapack_int ldv.
• lapack_complex_double *q — pointer to q, plus lapack_int ldq.

real talk: this manpage does not document what any of these actually do — no descriptions of jobu/jobv/jobq values, no meaning for tola/tolb, no output semantics for k and l. I refuse to invent lore. go read the real LAPACK docs for zggsvp3 before you call it, fr fr. 🙈

and the receipts: Definition at line 36 of file lapacke_zggsvp3.c. that's where she lives. 💅

🌈 a lil sign-off 🌈

this page is tagged Version 3.8.0, dated Tue Nov 14 2017, and it's the lapacke_zggsvp3.c manpage from the LAPACK set. go forth, pass all twenty arguments, and remember: twenty arguments is not a red flag, it's just her season. slay 🫶✨🍓
