CBLAS/src/cblas_stbsv.c(3)

💅 CBLAS/src/cblas_stbsv.c

okay so this is a page from the Library Functions Manual (that's the manual name, bestie, it's right there in the header) and it's all about CBLAS/src/cblas_stbsv.c — the little CBLAS shim file that wraps up the triangular band matrix solve situation. she's not the fancy one at the party but she's the one making it all work, yk? 🎀

✨ SYNOPSIS ✨

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

🧚 Macros

lowkey just a bunch of #defines doing the middleman thing:

#define F77_TA   &TA
#define F77_UL   &UL
#define F77_DI   &DI
#define F77_N   N
#define F77_K   K
#define F77_lda   lda
#define F77_incX   incX

🦋 Functions

and then the main character herself:

void API_SUFFIX cblas_stbsv (const CBLAS_LAYOUT layout, const CBLAS_UPLO
    Uplo, const CBLAS_TRANSPOSE TransA, const CBLAS_DIAG Diag, const
    CBLAS_INT N, const CBLAS_INT K, const float *A, const CBLAS_INT lda,
    float *X, const CBLAS_INT incX)

🌸 Macro Definition Documentation 🌸

here's the full rundown of every macro in the file, no gatekeeping 💖

• #define F77_DI &DI — nabs the address of DI, the diagonal argument.
• #define F77_incX incX — the incX stride, passed straight through, no middleman drama.
• #define F77_K K — the K band count, forwarded as-is.
• #define F77_lda lda — the lda leading dimension, also just passed along.
• #define F77_N N — the N size parameter, direct.
• #define F77_TA &TA — takes the address of TA (that's the transpose flag).
• #define F77_UL &UL — takes the address of UL (the upper/lower flag).

ngl these are literally just plumbing macros and that's iconic of them 🫶

👑 Function Documentation 👑

⭐ void API_SUFFIX cblas_stbsv (const CBLAS_LAYOUT layout, const CBLAS_UPLO Uplo, const CBLAS_TRANSPOSE TransA, const CBLAS_DIAG Diag, const CBLAS_INT N, const CBLAS_INT K, const float * A, const CBLAS_INT lda, float * X, const CBLAS_INT incX)

this is the function, okay? she takes a layout, a Uplo, a TransA, a Diag, an N, a K, a pointer to A, an lda, a pointer to X, and an incX — all exactly typed as shown above, with the const-ness where it belongs and X left mutable because she's going to write to it. main character behaviour fr fr. 💅

💜 and that's the whole page! reminder that the footer situation is: LAPACK, Version 3.12.0, source CBLAS/src/cblas_stbsv.c(3) — that's the version and the source, bestie, written down so you never forget. go forth and solve those triangular band systems, iykyk 🦋🌸🌈
