TESTING/LIN/zlqt05.f(3)

okay so bestie, welcome to TESTING/LIN/zlqt05.f, chilling in the Library Functions Manual. She's a LAPACK testing page and she's here to spill the tea about one subroutine. 💅

---

🌸 NAME 🌸

TESTING/LIN/zlqt05.f — that's the name, that's the vibe. ✨

✨ SYNOPSIS ✨

🎀 Functions/Subroutines 🎀

subroutine zlqt05 (m, n, l, nb, result)
    ZLQT05

🫶 Function/Subroutine Documentation 🫶

Here's the full signature, copied exactly because we do not play with code:

subroutine zlqt05 (integer m, integer n, integer l, integer nb, double
precision, dimension(6) result)

ZLQT05

🎀 Purpose 🎀

The page says: ZQRT05 tests ZTPLQT and ZTPMLQT. (Yes, ZQRT05 — that's literally what it says, bestie. 👀)

🍓 Parameters 🍓

• M is INTEGER — number of rows in lower part of the test matrix.
• N is INTEGER — number of columns in test matrix.
• L is INTEGER — the number of rows of the upper trapezoidal part the lower test matrix. 0 <= L <= M.
• NB is INTEGER — block size of test matrix. NB <= N.
• RESULT is DOUBLE PRECISION array, dimension (6) — results of each of the six tests below.

The six test results are exactly:

• 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 |

mwah 💋 and that's the whole page, bestie. This one is from LAPACK Version 3.12.0, source TESTING/LIN/zlqt05.f(3). The footer didn't give us an actual date, so no cap, we're not making one up. 🫶✨
