lapacke_cposvxx.c(3)

🎀 lapacke_cposvxx.c 🎀

okay so this page is from LAPACK — yes, that LAPACK — and it's the doc for lapacke_cposvxx.c, bestie. it's a C file, it's got one (1) function in it, and we're gonna go through the whole thing together, no skipping 💅

---

✨ NAME ✨

lapacke_cposvxx.c — that's it, that's the name, that's the whole vibe 🫶

---

🌸 SYNOPSIS 🌸

first thing you clock: it pulls in a header. literally one line:

#include 'lapacke_utils.h'

💜 Functions

and then boom, the function itself. she's long. she's iconic. she has twenty-three parameters. don't panic, we're listing every single one:

lapack_int LAPACKE_cposvxx (int matrix_layout, char fact, char uplo,
    lapack_int n, lapack_int nrhs, lapack_complex_float *a, lapack_int
    lda, lapack_complex_float *af, lapack_int ldaf, char *equed, float
    *s, lapack_complex_float *b, lapack_int ldb, lapack_complex_float
    *x, lapack_int ldx, float *rcond, float *rpvgrw, float *berr,
    lapack_int n_err_bnds, float *err_bnds_norm, float *err_bnds_comp,
    lapack_int nparams, float *params)

💖 Function Documentation 💖

🔥 lapack_int LAPACKE_cposvxx (...)

okay so the full signature, spelled out in all her glory, no crumbs left behind:

lapack_int LAPACKE_cposvxx (int matrix_layout, char fact, char uplo,
    lapack_int n, lapack_int nrhs, lapack_complex_float * a, lapack_int lda,
    lapack_complex_float * af, lapack_int ldaf, char * equed, float * s,
    lapack_complex_float * b, lapack_int ldb, lapack_complex_float * x,
    lapack_int ldx, float * rcond, float * rpvgrw, float * berr, lapack_int
    n_err_bnds, float * err_bnds_norm, float * err_bnds_comp, lapack_int
    nparams, float * params)

and here's the full cast, in the exact order they show up on stage — do not reshuffle them, fr fr, order matters:

• int matrix_layout — an int, bestie. that's the assignment. 📐
• char fact — a char. yes, a whole char for this.
• char uplo — also a char. she's short but she's important.
• lapack_int n — lapack_int number one.
• lapack_int nrhs — lapack_int number two.
• lapack_complex_float *a — pointer to a lapack_complex_float.
• lapack_int lda — yep, another one.
• lapack_complex_float *af — another lapack_complex_float pointer, different name, iconic.
• lapack_int ldaf — the lda-but-with-an-f of the group.
• char *equed — a char pointer this time 👀
• float *s — float pointer. tiny name. big presence.
• lapack_complex_float *b — back on the complex float grind.
• lapack_int ldb — mmhm.
• lapack_complex_float *x — the third lapack_complex_float pointer, she's the main character honestly.
• lapack_int ldx — the matching lapack_int, we stan a matched set.
• float *rcond — float pointer, say it with me.
• float *rpvgrw — also float *, and yes that spelling is correct, don't come for her 😭
• float *berr — float pointer number three.
• lapack_int n_err_bnds — the one lapack_int with the longest name, respect it.
• float *err_bnds_norm — float pointer.
• float *err_bnds_comp — float pointer, the comp one, keep the two straight 🦋
• lapack_int nparams — last lapack_int, we made it.
• float *params — and the very last parameter, a float pointer, curtain call 🎬

heads up: that's all the documentation gives you — the types, the names, and the order. no extra lore, no secret behaviour notes. if you need the semantics, that's a whole other source file, babe.

and the receipt: Definition at line 36 of file lapacke_cposvxx.c. 💀 line thirty-six. go look, she's really there.
