F77_TR(3)

💅 F77_TR(3) — like, the CBLAS cblas_cher2k page, bestie 🎀

okay so this is a Library Functions Manual page, and before you ask — yes, the title up there is literally F77_TR(3), and the whole thing lives under CBLAS/src/cblas_cher2k.c(3). It's a Doxygen-generated doc for one specific BLAS-ish routine, so it's giving "auto-generated reference material" energy, but we're gonna make it make sense. 🦋

✨ NAME ✨

CBLAS/src/cblas_cher2k.c — that's it, that's the name. The file itself is the main character here. 👑

🌸 SYNOPSIS 🌸

#include 'cblas.h'
#include 'cblas_f77.h'

🫶 Macros

here's the little macro squad, do not lose a single one:

#define F77_TR   &TR
#define F77_UL   &UL
#define F77_N   N
#define F77_K   K
#define F77_lda   lda
#define F77_ldb   ldb
#define F77_ldc   ldc

💖 Functions

void API_SUFFIX cblas_cher2k (const CBLAS_LAYOUT layout, const
    CBLAS_UPLO Uplo, const CBLAS_TRANSPOSE Trans, const CBLAS_INT N,
    const CBLAS_INT K, const void *alpha, const void *A, const CBLAS_INT
    lda, const void *B, const CBLAS_INT ldb, const float beta, void *C,
    const CBLAS_INT ldc)

look at that parameter list. it's long. it's iconic. we respect it. 😤

🧚 Macro Definition Documentation 🧚

okay so the macros get their own little section, and ngl they're just aliases — but we're listing every single one because that's the vibe:

• #define F77_K K — F77_K is just K. slay, no notes.
• #define F77_lda lda — F77_lda maps straight to lda.
• #define F77_ldb ldb — and F77_ldb to ldb.
• #define F77_ldc ldc — and F77_ldc to ldc.
• #define F77_N N — F77_N is N, periodt.
• #define F77_TR &TR — F77_TR is &TR, address-of and all. 💅
• #define F77_UL &UL — F77_UL is &UL, same deal.

🔥 Function Documentation 🔥

⭐ void API_SUFFIX cblas_cher2k ( ... )

void API_SUFFIX cblas_cher2k (const CBLAS_LAYOUT layout, const CBLAS_UPLO
    Uplo, const CBLAS_TRANSPOSE Trans, const CBLAS_INT N, const CBLAS_INT K,
    const void * alpha, const void * A, const CBLAS_INT lda, const void * B,
    const CBLAS_INT ldb, const float beta, void * C, const CBLAS_INT ldc)

the way this signature just keeps going 😭 every param is const except the ones that aren't, beta is a float while alpha is a void *, and C is the one getting written into. that's the whole story the manpage gives us — no extra lore, no invented details, fr fr.
