CBLAS/src/cblas_sgemm.c(3)

💅 CBLAS/src/cblas_sgemm.c(3) — the LAPACK girlies' guide

okay bestie, so this is a page out of the Library Functions Manual for CBLAS/src/cblas_sgemm.c, and honestly? it's giving "auto-generated but make it fashion" ✨ like the whole thing is a single header-ish file that wraps up the single-precision general matrix multiply, and I'm kind of obsessed 🫶

---

✨ NAME ✨

CBLAS/src/cblas_sgemm.c — that's literally it, that's the name, no long dramatic subtitle, the file speaks for itself 💁‍♀️

---

🌸 SYNOPSIS 🌸

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

🎀 Macros

the little #define glue that makes the Fortran call work, no cap:

#define F77_TA   &TA
#define F77_TB   &TB
#define F77_M   M
#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_sgemm (const CBLAS_LAYOUT layout, const
    CBLAS_TRANSPOSE TransA, const CBLAS_TRANSPOSE TransB, const
    CBLAS_INT M, const CBLAS_INT N, const CBLAS_INT K, const float
    alpha, const float *A, const CBLAS_INT lda, const float *B, const
    CBLAS_INT ldb, const float beta, float *C, const CBLAS_INT ldc)

🌈 Macro Definition Documentation 🌈

look at these babies, all documented one by one, alphabet-adjacent and thriving 👑

• #define F77_K K — passes K straight through to the Fortran side, lowkey just a rename but she's doing her job 💜
• #define F77_lda lda — same energy for lda, the leading dimension of A 🍓
• #define F77_ldb ldb — and here's ldb, leading dimension of B 🧚
• #define F77_ldc ldc — plus ldc, leading dimension of C, the whole trio ate 💅
• #define F77_M M — M goes through, unchanged, iconic ✨
• #define F77_N N — N too, matching set, periodt 💖
• #define F77_TA &TA — ooh this one takes the address of TA, note the &, because that's how the transpose flag gets passed along 🔥
• #define F77_TB &TB — and same for TB, address-of, &TB, matching bestie behaviour 🫶

⭐ Function Documentation ⭐

void API_SUFFIX cblas_sgemm (...)

here's the whole signature again, laid out all pretty, every single parameter present and accounted for, because we do not skip details in this house 😤

void API_SUFFIX cblas_sgemm (const CBLAS_LAYOUT layout, const
    CBLAS_TRANSPOSE TransA, const CBLAS_TRANSPOSE TransB, const CBLAS_INT M,
    const CBLAS_INT N, const CBLAS_INT K, const float alpha, const float *
    A, const CBLAS_INT lda, const float * B, const CBLAS_INT ldb, const
    float beta, float * C, const CBLAS_INT ldc)

and the receipts 🧾:

like, line 12, that's where it lives, that's the address, iykyk 📍

💀 Author 💀

not a human, not a person, not even a girlie — this one was:

Generated automatically by Doxygen for LAPACK from the source code.

so if you were about to @ someone and thank them for writing this by hand? don't 😭 it was Doxygen. it was always Doxygen. the machine ate and left no crumbs 🤖✨

and that's the whole page bestie, no notes, no cap 💖

tiny reminder: everything above is exactly what the page says — same macros, same signature, same line number, same author line — I just gave it a wardrobe upgrade 🎀
