ZCHKTSQR(3)

💅 ZCHKTSQR(3) — like, the manual page for zchktsqr.f, bestie 🎀

okay so real talk, we're deep in the LAPACK testing trenches here and the page header says this lives in the Library Functions Manual — the file is zchktsqr.f(3) and honestly it's giving "I test the testers" main character energy. Let's get into it ✨

🌸 SYNOPSIS 🌸

Functions/Subroutines

subroutine ZCHKTSQR (thresh, tsterr, nm, mval, nn, nval, nnb, nbval,
    nout)
    DCHKQRT

---

🦋 Function/Subroutine Documentation 🦋

subroutine ZCHKTSQR (double precision thresh, logical tsterr, integer nm,
    integer, dimension( * ) mval, integer nn, integer, dimension( * ) nval,
    integer nnb, integer, dimension( * ) nbval, integer nout)
    DCHKQRT

💖 Purpose 💖

okay so the whole point, no cap:

!>
!> ZCHKTSQR tests ZGEQR and ZGEMQR.
!>

that's it. that's the vibe check. she tests ZGEQR and ZGEMQR, periodt 🫶

✨ Parameters ✨

• THRESH — THRESH is DOUBLE PRECISION. This is the threshold value for the test ratios, bestie. A result gets included in the output file if RESULT >= THRESH. And if you literally want every single test ratio printed? Set THRESH = 0. iconic behaviour, zero gatekeeping 💅
• TSTERR — TSTERR is LOGICAL. It's the flag that indicates whether error exits are to be tested. yep, that's the whole job 🎀
• NM — NM is INTEGER. The number of values of M contained in the vector MVAL. count 'em 🦋
• MVAL — MVAL is INTEGER array, dimension (NM). These are the values of the matrix row dimension M. rows row rows ✨
• NN — NN is INTEGER. The number of values of N contained in the vector NVAL. slay 🫶
• NVAL — NVAL is INTEGER array, dimension (NN). The values of the matrix column dimension N. columns bestie 🌸
• NNB — NNB is INTEGER. The number of values of NB contained in the vector NBVAL. yes, NB. we love a blocksize 🌈
• NBVAL — NBVAL is INTEGER array, dimension (NNB). The values of the blocksize NB. blocky and proud 💜
• NOUT — NOUT is INTEGER. The unit number for output. where the receipts get written 📝

⭐ Author (again, but this time it's the generated-by energy) ⭐

Generated automatically by Doxygen for LAPACK from the source code. not a human author, a little robot did it for us, and honestly? werk 🙈

lowkey a reminder: THRESH = 0 prints every test ratio, so like… be ready for a lot of output if you go there 😭

and that's the page, bestie 💖 this was zchktsqr.f(3) from LAPACK, Version 3.12.0, source at /home/abui.../zchktsqr.f(3) — ty for coming to my ted talk, mwah 🎀✨
