SDRVGT(3)

🌸 SDRVGT(3) — like, the whole vibe 💅

okay so bestie, first thing: this page lives in the Library Functions Manual, and the file it's documenting is literally:

/home/abuild/rpmbuild/BUILD/lapack-static-3.12.0-build/lapack-3.12.0/TESTING/LIN/sdrvgt.f

like that's the whole path, no cap, she's long but she's worth it 🫶

✨ SYNOPSIS ✨

Functions/Subroutines 🦋

subroutine SDRVGT (dotype, nn, nval, nrhs, thresh, tsterr, a, af, b, x,
    xact, work, rwork, iwork, nout)
        SDRVGT

yes she's called SDRVGT, that's the name, that's the brand 💖

🎀 Function/Subroutine Documentation 🎀

subroutine SDRVGT (logical, dimension( * ) dotype, integer nn, integer,
    dimension( * ) nval, integer nrhs, real thresh, logical tsterr, real,
    dimension( * ) a, real, dimension( * ) af, real, dimension( * ) b, real,
    dimension( * ) x, real, dimension( * ) xact, real, dimension( * ) work,
    real, dimension( * ) rwork, integer, dimension( * ) iwork, integer nout)

SDRVGT ✨ (yes, again, she's iconic like that)

💜 Purpose 💜

!>
!> SDRVGT tests SGTSV and -SVX.
!>

that's it. that's the job. she tests SGTSV and -SVX and she does it well 💅

🌈 Parameters 🌈

• DOTYPE — ok so DOTYPE is a LOGICAL array, dimension (NTYPES). It's the "which matrix types are we even testing" list. Matrices of type j (for 1 <= j <= NTYPES) get tested if DOTYPE(j) = .TRUE.; but if DOTYPE(j) = .FALSE., then type j is literally not used. not invited to the party. 🙈
• NN — NN is INTEGER. It's the number of values of N contained in the vector NVAL. basically the headcount 🧚
• NVAL — NVAL is INTEGER array, dimension (NN). These are the values of the matrix dimension N. the sizes, the moments 👑
• NRHS — NRHS is INTEGER. The number of right hand sides, NRHS >= 0. no negatives bestie, we don't do that here 🍓
• THRESH — THRESH is REAL. It's the threshold value for the test ratios. A result gets included in the output file if RESULT >= THRESH. and if you want every single test ratio printed? use THRESH = 0. full transparency era 🔥
• TSTERR — TSTERR is LOGICAL. Flag that indicates whether error exits are to be tested. are we vibe-checking the error paths or not 💀
• A — A is REAL array, dimension (NMAX*4). as promised ✨
• AF — AF is REAL array, dimension (NMAX*4). also as promised 💖
• B — B is REAL array, dimension (NMAX*NRHS).
• X — X is REAL array, dimension (NMAX*NRHS).
• XACT — XACT is REAL array, dimension (NMAX*NRHS). the exact one, the realest one 🫶
• WORK — WORK is REAL array, dimension

(NMAX*max(3,NRHS))

• RWORK — RWORK is REAL array, dimension

(max(NMAX,2*NRHS))

• IWORK — IWORK is INTEGER array, dimension (2*NMAX).
• NOUT — NOUT is INTEGER. The unit number for output. where the receipts go 📬

ok bestie that's the whole page!! 💖 this is LAPACK, Version 3.12.0, and the little footer tag was /home/abui...IN/sdrvgt.f(3) — yes the path is abbreviated with ... in the middle, that's just how she's filed, don't come for her 😭 go forth and test those gtsv routines, periodt 🌈🎀
