CBLAS_SGEMMTR.C(3)

💅 CBLAS/src/...s_sgemmtr.c(3) — from the Library Functions Manual, bestie

okay so this is one of those auto-generated pages from the CBLAS corner of the LAPACK universe, and honestly? it's giving "the Doxygen machine wrote this at 3am and we're just living in it." but don't worry — we're gonna walk through every single thing on here together, no skips, no skimming, fr fr. 🫶

✨ NAME ✨

CBLAS/src/cblas_sgemmtr.c

that's it. that's the name. it's the source file itself, living its best life as a manpage. iconic behavior honestly 🎀

---

🌸 SYNOPSIS 🌸

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

like, you gotta include both, okay? both of them. 'cblas.h' AND 'cblas_f77.h'. the quotes are single quotes in the original and we are NOT changing them, periodt. 💅

🦋 Macros

okay so these little define guys are the glue between the C world and the Fortran world, and they are literally just address-of and plain-alias macros. here's the whole set, exactly as written:

• #define F77_TA → &TA
• #define F77_TB → &TB
• #define F77_UL → &UL
• #define F77_N → N
• #define F77_K → K
• #define F77_lda → lda
• #define F77_ldb → ldb
• #define F77_ldc → ldc

notice how TA, TB and UL get the & (they're pointers to the enums, bestie) while N, K, and all the ld* values are passed straight through like the confident main characters they are ✨

💜 Functions

there's exactly one function here and she's the whole point of the page:

void API_SUFFIX cblas_sgemmtr (const CBLAS_LAYOUT layout, const
    CBLAS_UPLO Uplo, const CBLAS_TRANSPOSE TransA, const CBLAS_TRANSPOSE
    TransB, 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)

look at her. fourteen parameters. fourteen!! that's not a function, that's a whole group chat. 😭 but she's void, so no return value to worry about — she just does her thing and leaves. no cap.

🎀 Macro Definition Documentation 🎀

okay so the docs section lists the macros again (yes, again — Doxygen loves a re-run) and the order here is a little different from the synopsis, so here she is in the doc's own order:

• #define F77_K → K
• #define F77_lda → lda
• #define F77_ldb → ldb
• #define F77_ldc → ldc
• #define F77_N → N
• #define F77_TA → &TA
• #define F77_TB → &TB
• #define F77_UL → &UL

same eight macros, same values, just shuffled. think of it as the director's cut 💅

🔥 Function Documentation 🔥

⭐ void API_SUFFIX cblas_sgemmtr (...)

the full signature, one more time, all official and everything:

void API_SUFFIX cblas_sgemmtr (const CBLAS_LAYOUT layout, const CBLAS_UPLO
    Uplo, const CBLAS_TRANSPOSE TransA, const CBLAS_TRANSPOSE TransB, 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)

bestie, we're told Definition at line 13 of file cblas_sgemmtr.c. line thirteen!! spooky season energy, lowkey 👻

heads up: this page gives you the signature and the macros and literally nothing else in the way of behaviour description. no math spelled out, no error conditions, no return values (it's void anyway), no examples, no SEE ALSO, no environment variables, no exit statuses. so if you were waiting for the plot twist — there isn't one. this is the whole page, and we've covered every crumb of it. 🍓

👑 Author 👑

Generated automatically by Doxygen for LAPACK from the source code.

so yeah — nobody wrote this, a robot did, from the actual source code. she's a bot-written baddie and we respect her for it 🤖💖

and that's the whole thing, bestie! absolute full coverage, nothing dropped, nothing invented. this gem is from LAPACK, Version 3.12.0, on the page CBLAS/src/...s_sgemmtr.c(3) — treat her well, and remember: line 13 is where it all happens 💅✨🦋
