💅 NAME

TESTING/LIN/zerrrfp.f — bestie, this is a whole file in the LAPACK testing folder, and it's the one that runs the error-exit checks for the COMPLEX*16 driver routines. Yes, that kind of testing. The "does it scream correctly when you feed it garbage" kind. Iconic behaviour, honestly.

✨ SYNOPSIS ✨

🎀 Functions/Subroutines

  • subroutine zerrrfp (nunit) — literally just the one, and her name is ZERRRFP. Main character energy, no supporting cast.

🦋 Function/Subroutine Documentation

subroutine zerrrfp (integer nunit)

Her full signature, verbatim, because we do not play about types around here:

subroutine zerrrfp (integer nunit)

🌸 ZERRRFP

💖 Purpose:

!>
!> ZERRRFP tests the error exits for the COMPLEX*16 driver routines
!> for solving linear systems of equations.
!>
!> ZDRVRFP tests the COMPLEX*16 LAPACK RFP routines:
!>     ZTFSM, ZTFTRI, ZHFRK, ZTFTTP, ZTFTTR, ZPFTRF, ZPFTRS, ZTPTTF,
!>     ZTPTTR, ZTRTTF, and ZTRTTP
!>

So what's the tea? ZERRRFP is out here testing the error exits for the COMPLEX*16 driver routines that solve linear systems of equations. Like, she's not solving anything — she's the vibe check. She pokes the routines with bad input and makes sure they bail out properly instead of doing something cursed. 🫶

And the comment block says ZDRVRFP tests the COMPLEX*16 LAPACK RFP routines — here's the full squad, all eleven of them, no cap:

  • ZTFSM
  • ZTFTRI
  • ZHFRK
  • ZTFTTP
  • ZTFTTR
  • ZPFTRF
  • ZPFTRS
  • ZTPTTF
  • ZTPTTR
  • ZTRTTF
  • ZTRTTP

Periodt. Eleven routines, all accounted for, all getting their error paths tested. 💅

🧚 Parameters

NUNIT

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

Lowkey important: NUNIT is an INTEGER, and it's the unit number for output — that's where all the pass/fail receipts get printed. So if you're wondering "where do the messages go?", the answer is: wherever you pointed NUNIT. ✨

Ok so real talk: everything above is straight from the source — Version 3.12.0 of LAPACK, page TESTING/LIN/zerrrfp.f(3) — so go off, test those error exits, and remember: if NUNIT isn't set to somewhere you can actually read, you're gonna be debugging blind. Slay responsibly. 🍓🔥

mwah 💋 — auto-generated, version 3.12.0, catch you on the next manpage
