ZERRTSQR(3)

📦 version 3.12.0, in opensuse-leap 16.0

🌸 NAME 🌸

okay so bestie, this page is ZERRTSQR(3), and it lives in the Library Functions Manual — yes, that's the manual name, welcome to the party. 🎀 The header path situation is /home/abui.../zerrtsqr.f(3), and the NAME line is literally this file path, character for character (line break included, do not @ me):

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

That's it. That's the name. Slay. 💅

✨ SYNOPSIS ✨

🧚 Functions/Subroutines 🧚

The vibe is:

subroutine ZERRTSQR (path, nunit)
    ZERRTSQR

So you got ZERRTSQR, taking path and nunit, and then the subroutine name again for emphasis. Periodt. 💖

🦋 Function/Subroutine Documentation 🦋

The actual signature is:

subroutine ZERRTSQR (character*3 path, integer nunit)
    ZERRTSQR

🎀 Purpose 🎀

The purpose block is exactly this, and it says ZOUBLE — that's the original spelling, I'm not fixing it:

!>
!> ZERRTSQR tests the error exits for the ZOUBLE PRECISION routines
!> that use the TSQR decomposition of a general matrix.
!>

So: ZERRTSQR tests the error exits for the ZOUBLE PRECISION routines that use the TSQR decomposition of a general matrix. Highkey a testing icon. 🔥

💅 Parameters 💅

  • PATH — PATH is CHARACTER*3. It's the LAPACK path name for the routines to be tested. 👑
  • NUNIT — NUNIT is INTEGER. It's the unit number for output. 🎀

The original parameter comments are literally those type lines and descriptions, bestie — no extra flags hiding here.

okay that's the whole page, bestie. Cute sign-off time: this is LAPACK, Version 3.12.0, and the footer path is /home/abui.../zerrtsqr.f(3) — no date printed on this footer, so I'm not inventing one. Mwah 💋🎀
