🌸 /home/abui.../sdrvrf4.f(3) 🌸

okay so this is a page from the Library Functions Manual (yes that's the manual name, we're fancy here) and bestie, it's a whole LAPACK test driver. buckle up 💖

✨ NAME ✨

/home/abuild/rpmbuild/BUILD/lapack-static-3.12.0-build/lapack-3.12.0/TESTING/LIN/sdrvrf4.f

like, that's the whole name. the entire path. it's giving "my mom named me after the street she grew up on" energy 😭 but no cap, that's literally it — a Fortran file living in the LAPACK testing directory.

🦋 SYNOPSIS 🦋

Functions/Subroutines

subroutine SDRVRF4 (nout, nn, nval, thresh, c1, c2, ldc, crf, a, lda,
    s_work_slange)
    SDRVRF4

that's the vibe check right there ✨ one subroutine, eleven arguments, and a name that's just SDRVRF4 and nothing else (no short description, she said "figure it out" 💅).

🎀 Function/Subroutine Documentation 🎀

subroutine SDRVRF4

here's the full signature, character for character, because we do not play about accuracy 🫶

subroutine SDRVRF4 (integer nout, integer nn, integer, dimension( nn ) nval,
    real thresh, real, dimension( ldc, * ) c1, real, dimension( ldc, *) c2,
    integer ldc, real, dimension( * ) crf, real, dimension( lda, * ) a,
    integer lda, real, dimension( * ) s_work_slange)

SDRVRF4

🌈 Purpose: 🌈

!>
!> SDRVRF4 tests the LAPACK RFP routines:
!>     SSFRK
!>

so like, that's the whole point of her. she's the test girlie for the LAPACK RFP routines — specifically SSFRK. iconic behavior, testing the math so we don't have to 🔥

💜 Parameters 💜

• NOUT — NOUT is INTEGER ✨ and it's The unit number for output. — that's where all the results get written, bestie, the whole output situation.
• NN — NN is INTEGER ✨ The number of values of N contained in the vector NVAL. so like, how many sizes are we testing? that number. periodt.
• NVAL — NVAL is INTEGER array, dimension (NN) ✨ The values of the matrix dimension N. all the N values, lined up in a little array, ready to go 🎀
• THRESH — THRESH is REAL ✨ The threshold value for the test ratios. A result is included in the output file if RESULT >= THRESH. To have every test ratio printed, use THRESH = 0. — so like, the filter. if a result doesn't clear the bar she simply does not make the cut 💅. and if you're nosy and want everything? THRESH = 0. you're welcome 😌
• C1 — C1 is REAL array, ✨ dimension (LDC,NMAX)
• C2 — C2 is REAL array, ✨ dimension (LDC,NMAX) — yes she's got a twin, they come as a set 🫶
• LDC — LDC is INTEGER ✨ The leading dimension of the array A. followed by LDA >= max(1,NMAX). — and ngl that's exactly what the page says, talking about A and LDA in the middle of the LDC entry. not me questioning the documentation 😭 we report, we don't editorialize.
• CRF — CRF is REAL array, ✨ dimension ((NMAX*(NMAX+1))/2). that packed triangular life, so efficient, she ate 💀
• A — A is REAL array, ✨ dimension (LDA,NMAX)
• LDA — LDA is INTEGER ✨ The leading dimension of the array A. LDA >= max(1,NMAX). — there it is again, loud and clear this time.
• S_WORK_SLANGE — S_WORK_SLANGE is REAL array, dimension (NMAX) ✨ the work array, doing the invisible labor, main character energy honestly 👑

Generated automatically by Doxygen for LAPACK from the source code. — yeah, no human wrote this page, a robot did, and honestly? she did a pretty good job 🧚

that's the whole page bestie, every flag, every dimension, every max(1,NMAX), nothing skipped 🫶💅

— 💖 with love, from LAPACK, Version 3.12.0, dated /home/abui.../sdrvrf4.f(3) — catch you on the next page, mwah 🎀✨
