CBLAS/src/cblas_dgemm.c(3)

💅 CBLAS/src/cblas_dgemm.c — like, the whole manual page, bestie

okay so this is a page from the Library Functions Manual for CBLAS/src/cblas_dgemm.c, and yes it's as niche as it sounds, but stick with me because it's actually kind of iconic 💖

---

✨ NAME ✨

CBLAS/src/cblas_dgemm.c — that's it, that's the name, no cap 🫶

---

🌸 SYNOPSIS 🌸

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

🎀 Macros

these are the little shortcut gremlins that get defined, all eight of them, no skips:

#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

there's literally one function and she's the main character:

void API_SUFFIX cblas_dgemm (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 double
    alpha, const double *A, const CBLAS_INT lda, const double *B, const
    CBLAS_INT ldb, const double beta, double *C, const CBLAS_INT ldc)

look at her. all those const qualifiers? that's called boundaries, and she has them 💅

---

💫 MACRO DEFINITION DOCUMENTATION 💫

so this section is just the macros again, doing their little encore. here they are, all named and defined, exactly as they appear:

#define F77_K K

#define F77_lda lda

#define F77_ldb ldb

#define F77_ldc ldc

#define F77_M M

#define F77_N N

#define F77_TA &TA

#define F77_TB &TB

no notes, they're doing great, they're just passing the values through to the Fortran side like little messengers 🧚

🔥 FUNCTION DOCUMENTATION 🔥

void API_SUFFIX cblas_dgemm (...)

here's the full signature again because she deserves a second entrance, honestly:

void API_SUFFIX cblas_dgemm (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 double alpha, const double *
    A, const CBLAS_INT lda, const double * B, const CBLAS_INT ldb, const
    double beta, double * C, const CBLAS_INT ldc)

and where does she live? Definition at line 12 of file cblas_dgemm.c. 📍 like, line twelve. practically the front door. queen behavior 👑

real talk: this page is a reference stub, so it tells you the exact signature and where it's defined, but it doesn't spill the algorithm tea. that's a different page's job 🙈

👑 AUTHOR 👑

Generated automatically by Doxygen for LAPACK from the source code.

so nobody hand-wrote this, it's a Doxygen baddie doing her automated thing. we respect the pipeline ✨

that's the whole page, bestie, every macro, every signature, every word 🌈

signing off with the deets: this was LAPACK, Version 3.12.0, page CBLAS/src/cblas_dgemm.c(3) — stay slay, stay compiled, and remember: const on your pointers is self-care 💜🎀
