ZQRT05(3)

💅 NAME

okay so bestie, this is the manual page for /home/abuild/rpmbuild/BUILD/lapack-static-3.12.0-build/lapack-3.12.0/TESTING/LIN/zqrt05.f — yes that's the whole entire path, she's long, she's iconic, we respect her 🫶 (the page itself is filed under the cute little shorthand /home/abui...IN/zqrt05.f(3), iykyk).

✨ SYNOPSIS ✨

Functions/Subroutines

subroutine ZQRT05 (m, n, l, nb, result)

ZQRT05 — that's her, that's the whole vibe 💖

---

🎀 Function/Subroutine Documentation 🎀

subroutine ZQRT05 (integer m, integer n, integer l, integer nb, double
    precision, dimension(6) result)

ZQRT05 🦋

🌸 Purpose:

!>
!> ZQRT05 tests ZTPQRT and ZTPMQRT.
!>

literally that's it, that's her job — she's the test queen for ZTPQRT and ZTPMQRT, no cap 👑

🌈 Parameters

• M — lowkey the row count, bestie:

!>          M is INTEGER
!>          Number of rows in lower part of the test matrix.
!>

• N — the column situation:

!>          N is INTEGER
!>          Number of columns in test matrix.
!>

• L — this one's about the upper trapezoidal part:

!>          L is INTEGER
!>          The number of rows of the upper trapezoidal part the
!>          lower test matrix.  0 <= L <= M.
!>

heads up: 0 <= L <= M, respected boundaries only 💅

• NB — block size era:

!>          NB is INTEGER
!>          Block size of test matrix.  NB <= N.
!>

and yes, NB <= N — she said what she said 🎀

• RESULT — the moment of truth, six whole tests, she ate:

!>          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 |
!>

so RESULT is a DOUBLE PRECISION array, dimension (6), one slot per test — slay 💜
