🌸 TESTING/LIN/zqrt04.f(3) 🌸

okay so this is the TESTING/LIN/zqrt04.f(3) page from the Library Functions Manual — manual-name folded in right here, bestie, no shady top-line copy-paste. It's the manual entry for zqrt04, and it's literally the test-subroutine page for ZGEQRT and ZGEMQRT. 💅✨

✨ NAME ✨

TESTING/LIN/zqrt04.f — that's the name, that's the file, that's the vibe. 🎀

🦋 SYNOPSIS 🦋

Functions/Subroutines

• subroutine zqrt04 (m, n, nb, result) — ZQRT04

💖 Function/Subroutine Documentation 💖

subroutine zqrt04 (integer m, integer n, integer nb, double precision, dimension(6) result)

ZQRT04

Purpose:

ZQRT04 tests ZGEQRT and ZGEMQRT.

Parameters

• M — M is INTEGER; number of rows in test matrix. 📏
• N — N is INTEGER; number of columns in test matrix. 📐
• NB — NB is INTEGER; block size of test matrix. NB <= Min(M,N). Important little inequality, bestie. 🧱
• RESULT — RESULT is DOUBLE PRECISION array, dimension (6); results of each of the six tests below. 👑
  • RESULT(1) = | A - Q R |
  • RESULT(2) = | I - Q^H Q |
  • 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 |

The footer flex is LAPACK Version 3.12.0 plus TESTING/LIN/zqrt04.f(3) — that's the source/version line, and there's no date printed in it, so we're not inventing one. Bye bestie, slay your tests 💖🦋✨
