DLQT05(3)

💅 NAME 💅

okay so bestie, this is DLQT05(3) from the Library Functions Manual — yes, the whole page is for this one Fortran subroutine. The file on the NAME line is:

/home/abuild/rpmbuild/BUILD/lapack-static-3.12.0-build/lapack-3.12.0/TESTING/LIN/dlqt05.f

That's the source-file path, periodt. 💖

✨ SYNOPSIS ✨

Functions/Subroutines

subroutine DLQT05 (m, n, l, nb, result)
    DLQT05

---

🎀 Function/Subroutine Documentation 🎀

here's the full signature, bestie — look at all those arguments:

subroutine DLQT05 (integer m, integer n, integer l, integer nb, double precision, dimension(6) result)
    DLQT05

🌸 Purpose 🌸

The source purpose block says, and I quote:

!>
!> DQRT05 tests DTPLQT and DTPMLQT.
!>

warning: yes, it says DQRT05 with a Q in that purpose line while the routine is DLQT05 — that's literally what the original says, so I'm not touching it, iykyk. 😭

👑 Parameters 👑

• M — M is INTEGER; it's the number of rows in the lower part of the test matrix. slay. 💅
• N — N is INTEGER; the number of columns in the test matrix. cute. ✨
• L — L is INTEGER; the number of rows of the upper trapezoidal part the lower test matrix. The bound is exactly 0 <= L <= M. no cap.
• NB — NB is INTEGER; block size of test matrix. Exact bound: NB <= N. 🎀
• RESULT — RESULT is DOUBLE PRECISION array, dimension (6); these are the 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 |

💌 okay that's the whole page! The footer/version line says LAPACK Version 3.12.0, and the footer path is /home/abui...IN/dlqt05.f(3). No separate date is printed there, so I'm not inventing one — just the version and path that are actually there, bestie. bye! 🫶✨
