💅 CBLAS/src/cblas_zhpmv.c(3) — Library Functions Manual

okay bestie, so this is a page from the CBLAS manual (that's the C interface to LAPACK, iykyk) and honestly? it's a whole vibe. it's short, it's sweet, it's giving "auto-generated documentation but make it fashion." let's get into it 🎀

---

✨ NAME ✨

CBLAS/src/cblas_zhpmv.c — that's it, that's the name. this file is literally the main character and it knows it 👑

---

🌸 SYNOPSIS 🌸

here's everything this file pulls in and hands out, bestie:

#include <stdio.h>
#include <stdlib.h>
#include 'cblas.h'
#include 'cblas_f77.h'

heads up: yes, stdio.h and stdlib.h are in angle brackets and cblas.h and cblas_f77.h are in single quotes — that's exactly how it's written here, so don't come for me 🙈

🦋 Macros

the little shortcut squad, fr fr:

#define F77_UL   &UL
#define F77_N   N
#define F77_incX   incx
#define F77_incY   incY

🧚 Functions

the one (1) function on this whole page, and she's iconic:

void API_SUFFIX cblas_zhpmv (const CBLAS_LAYOUT layout, const CBLAS_UPLO
    Uplo, const CBLAS_INT N, const void *alpha, const void *AP, const
    void *X, const CBLAS_INT incX, const void *beta, void *Y, const
    CBLAS_INT incY)

🍓 Macro Definition Documentation 🍓

these get their own little section and honestly they deserve it 💖

• #define F77_incX incx — just maps F77_incX straight onto incx. no thoughts, no math, just vibes ✨
• #define F77_incY incY — same energy for the Y side: F77_incY becomes incY 🌈
• #define F77_N N — F77_N is literally just N. a re-naming. a glow-up with zero effort 💅
• #define F77_UL &UL — this one's fancy, she takes the address: F77_UL expands to &UL 🔥

🔥 Function Documentation 🔥

void API_SUFFIX cblas_zhpmv (const CBLAS_LAYOUT layout, const CBLAS_UPLO Uplo, const CBLAS_INT N, const void * alpha, const void * AP, const void * X, const CBLAS_INT incX, const void * beta, void * Y, const CBLAS_INT incY)

okay so here's the whole squad of parameters laid out for you, no cap:

• const CBLAS_LAYOUT layout
• const CBLAS_UPLO Uplo
• const CBLAS_INT N
• const void * alpha
• const void * AP
• const void * X
• const CBLAS_INT incX
• const void * beta
• void * Y
• const CBLAS_INT incY

and the crucial detail, bestie, don't skip it: Definition at line 12 of file cblas_zhpmv.c. line twelve. twelve. remember it for the quiz 🫶

ngl this page tells you the signature but not a single word about what the math actually does — that's just how it is here, so I'm not gonna invent lore. take it up with the source file 🙈

⭐ cute sign-off ⭐

and that's the page!! 🎀 this gem is from LAPACK, Version 3.12.0, and the page itself is CBLAS/src/cblas_zhpmv.c(3) — go forth and call your BLAS routines, bestie, you're gonna slay 💅✨🦋
