TESTING/LIN/dlqt05.f(3)

💅 TESTING/LIN/dlqt05.f — like, the whole manual, but make it make sense

okay bestie, welcome to TESTING/LIN/dlqt05.f from the Library Functions Manual ✨ this one's short and sweet and honestly kind of iconic — it's a test routine that checks whether two other routines are doing their job. main character energy fr fr 🎀

✨ SYNOPSIS ✨

Functions/Subroutines

• subroutine dlqt05 (m, n, l, nb, result) — the one and only, DLQT05 herself 👑

---

🦋 Function/Subroutine Documentation 🦋

subroutine dlqt05 (integer m, integer n, integer l, integer nb, double precision, dimension(6) result)

DLQT05 💖

🎯 Purpose 🎯

DQRT05 tests DTPLQT and DTPMLQT. that's it, that's the whole vibe — she's a vibe check for those two 🫶

🌸 Parameters 🌸

• M — M is INTEGER. number of rows in the lower part of the test matrix. lowkey the tall part 🌈
• N — N is INTEGER. number of columns in the test matrix. the width, iykyk 💜
• L — L is INTEGER. the number of rows of the upper trapezoidal part of the lower test matrix. constraint check bestie: 0 <= L <= M ✅
• NB — NB is INTEGER. block size of the test matrix. constraint check again: NB <= N ✅
• RESULT — RESULT is DOUBLE PRECISION array, dimension (6). this is where all six test results land, one per slot 🍓 here's the lineup, no cap:
  • 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 |
