💖 TESTING/LIN/ztsqr01.f(3) 💖

Okay bestie, welcome to the Library Functions Manual page for TESTING/LIN/ztsqr01.f(3) — manual name folded in right here like a little name tag. This is the group chat for ztsqr01, and it’s lowkey giving main character energy in the LAPACK testing directory. 💅✨

---

🌸 NAME 🌸

TESTING/LIN/ztsqr01.f — that’s the file, bestie. That’s the name. No cap. 🎀

🦋 SYNOPSIS 🦋

Functions/Subroutines

subroutine ztsqr01 (tssw, m, n, mb, nb, result)

And the subroutine’s short label is ZTSQR01. Slay. 👑

✨ Function/Subroutine Documentation ✨

subroutine ztsqr01 (character tssw, integer m, integer n, integer mb, integer nb, double precision, dimension(6) result)

ZTSQR01 — yes, again, the name. Not me being extra, the original is extra. 💅

🎯 Purpose

ZTSQR01 tests ZGEQR , ZGELQ, ZGEMLQ and ZGEMQR. That’s it, that’s the assignment. It’s giving very focused tester energy. 🔥

🧪 Parameters

• TSSW — TSSW is CHARACTER. Set it to 'TS' when you’re testing tall skinny QR, and anything else when you’re testing short wide LQ. Vibe check via character flag, iykyk. 🌈
• M — M is INTEGER, and it’s the number of rows in the test matrix. Rows? Slay. 📏
• N — N is INTEGER, and it’s the number of columns in the test matrix. Columns? Also slay. 🎀
• MB — MB is INTEGER, and it’s the number of row in row block in test matrix. That’s the original wording — “row,” singular, bestie. We don’t edit. 🫶
• NB — NB is INTEGER, and it’s the number of columns in column block test matrix. Again, exact original energy. 💜
• RESULT — RESULT is a DOUBLE PRECISION array, dimension (6). It holds the results of each of the six tests below. Periodt:
  • RESULT(1) = | A - Q R | or | A - L Q |
  • RESULT(2) = | I - Q^H Q | or | I - Q Q^H |
  • RESULT(3) = | Q C - Q C |
  • RESULT(4) = | Q^H C - Q^H C |
  • RESULT(5) = | C Q - C Q |
  • RESULT(6) = | C Q^H - C Q^H |

Okay that’s the whole page! 💖 Source/version tea: this is from LAPACK, Version 3.12.0, on the TESTING/LIN/ztsqr01.f(3) page. The footer doesn’t give a separate date, ngl, but it does say it was generated automatically by Doxygen for LAPACK from the source code. Bye bestie, go test those QR/LQ routines! 🎀✨🦋
