ZERRTZ(3)

💅 ZERRTZ(3) — zerrtz.f, bestie, like the whole manual

okay so this is a Library Functions Manual page, and before we even get into it — the filename is a whole journey:

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

that's the header path too, /home/abui...IN/zerrtz.f(3), which is giving "the terminal truncated my whole personality." anyway. sit down, hydrate, let's get into it 🫶

✨ NAME ✨

/home/abuild/rpmbuild/BUILD/lapack-static-3.12.0-build/lapack-3.12.0/TESTING/LIN/zerrtz.f — that's the name, that's the whole name, no notes. it's a Fortran file living its best life in the LAPACK testing directory and honestly? iconic. 👑

---

🦋 SYNOPSIS 🦋

Functions/Subroutines

one (1) subroutine, and she is:

subroutine ZERRTZ (path, nunit)

her name is ZERRTZ. she takes path and nunit. that's the vibe check, we passed it. ✅

---

🎀 Function/Subroutine Documentation 🎀

subroutine ZERRTZ (character*3 path, integer nunit)

ZERRTZ — spelled out in full with her actual types, because we don't do vague here. path is a character*3 and nunit is an integer. noted, memorized, tattooed. 💖

Purpose:

!>
!> ZERRTZ tests the error exits for ZTZRZF.
!>

so what's her job? literally just: ZERRTZ tests the error exits for ZTZRZF. that's it. that's the whole purpose. she's the error-exit tester for ZTZRZF and she's not pretending to be anything else. main character energy, minimal plot. no cap. 🔥

Parameters

• PATH — is CHARACTER*3. this is the LAPACK path name for the routines to be tested. like, which routines are we testing, bestie? that's what PATH tells us. 🌸

!>          PATH is CHARACTER*3
!>          The LAPACK path name for the routines to be tested.
!>

• NUNIT — is INTEGER. this is the unit number for output. yes, the humble unit number. every test needs somewhere to spill its tea. ☕

!>          NUNIT is INTEGER
!>          The unit number for output.

⭐ Author ⭐

okay and then there's the meta-author section, which is like the author of the author:

Generated automatically by Doxygen for LAPACK from the source code.

yep — automatically generated by Doxygen for LAPACK, straight from the source code. she didn't write her own bio. she was generated. we respect that. 💅

---

lowkey a gentle reminder: this page is a generated doc for a test subroutine, so don't go treating it as a promise of behaviour beyond "tests the error exits for ZTZRZF." iykyk. 💜

and that's the whole page! 💖 brought to you by LAPACK, Version 3.12.0, dated /home/abui...IN/zerrtz.f(3) — the footer said it, i said it, we all said it. mwah 🎀✨
