TESTING/LIN/dqrt05.f(3)

💖 NAME 💖

okay so this is the page for TESTING/LIN/dqrt05.f(3), and it lives in the Library Functions Manual — manual name folded in near the top like a little ribbon. 🎀 The star is the dqrt05 subroutine, and its whole thing is testing DTPQRT and DTPMQRT. Vibe check: lowkey iconic testing-era main character energy. Periodt. 💅

✨ SYNOPSIS ✨

🦋 Functions/Subroutines 🦋

subroutine dqrt05 (m, n, l, nb, result)

That's the whole call, bestie. 👑

🌸 Function/Subroutine Documentation 🌸

   subroutine dqrt05 (integer m, integer n, integer l, integer nb, double
       precision, dimension(6) result)

DQRT05 — say hi. 👋

✨ Purpose ✨

DQRT05 tests DTPQRT and DTPMQRT. That's the mission, and honestly? It ate. 💅 The source has this purpose note wrapped in !> comment markers, like !> DQRT05 tests DTPQRT and DTPMQRT. 💖

🎀 Parameters 🎀

• M — M is INTEGER; this is the number of rows in the lower part of the test matrix. ⭐
• N — N is INTEGER; this is the number of columns in the test matrix. 🦋
• L — L is INTEGER; the number of rows of the upper trapezoidal part the lower test matrix. 0 <= L <= M. Keep that range in your notes, bestie. 📝
• NB — NB is INTEGER; block size of the test matrix. NB <= N. 🧚
• 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 |
