/home/abui.../stsqr01.f(3) 🌸

okay so bestie, this page is chilling in the Library Functions Manual — manual name folded in near the top like a little ribbon 🎀 — and it's all about the STSQR01 subroutine. No cap, it's giving LAPACK test-matrix energy.

✨ NAME ✨

/home/abuild/rpmbuild/BUILD/lapack-static-3.12.0-build/lapack-3.12.0/TESTING/LIN/stsqr01.f

That's the full path, literally right there 💅

🌈 SYNOPSIS 🌈

💅 Functions/Subroutines 💅

   Functions/Subroutines
       subroutine STSQR01 (tssw, m, n, mb, nb, result)
           STSQR01

---

🛠️ Function/Subroutine Documentation 🛠️

   subroutine STSQR01 (character tssw, integer m, integer n, integer mb,
       integer nb, real, dimension(6) result)
       STSQR01

🎀 Purpose 🎀

The purpose block, verbatim vibes:

!>
!> DTSQR01 tests DGEQR , DGELQ, DGEMLQ and DGEMQR.
!>

Yes bestie, it says DTSQR01 in the purpose block — we keep it exactly like that 👀

🍓 Parameters 🍓

• TSSW — TSSW is CHARACTER. 'TS' is for testing tall skinny QR, and anything else is for testing short wide LQ. 🌈
• M — M is INTEGER. Number of rows in test matrix. 📏
• N — N is INTEGER. Number of columns in test matrix. 📐
• MB — MB is INTEGER. Number of row in row block in test matrix. 🧱
• NB — NB is INTEGER. Number of columns in column block test matrix. 🎛️
• RESULT — RESULT is REAL array, dimension (6). Results of each of the six tests below. 💖

And here are the six results, exactly as written:

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 |
