💖 NAME 💖

okay so bestie, welcome to xerbla(3) from the Library Functions Manual — this is the LAPACK error-reporting page, and it is lowkey iconic for being extremely direct. xerbla is literally the “xerbla: error reporting” situation. 🫶

✨ SYNOPSIS ✨

🎀 Functions 🎀

  • subroutine xerbla (srname, info) — XERBLA. 👑

🦋 Detailed Description 🦋

There’s no extra prose in this section on this page — the actual function lore is right below in Function Documentation. 💅

🔥 Function Documentation 🔥

subroutine xerbla (character*(*) srname, integer info)

XERBLA

🍓 Purpose 🍓

The source comment is giving very blunt main character energy:

!>
!> XERBLA  is an error handler for the LAPACK routines.
!> It is called by an LAPACK routine if an input parameter has an
!> invalid value.  A message is printed and execution stops.
!>
!> Installers may consider modifying the STOP statement in order to
!> call system-specific exception-handling facilities.
!>

Translation, bestie: XERBLA is LAPACK's error handler. An LAPACK routine calls it when an input parameter has an invalid value. A message is printed, and execution stops. No cap. 💀 The installer note is real too: installers may consider modifying the STOP statement so it calls system-specific exception-handling facilities. 🫶

🌸 Parameters 🌸

  • SRNAME — SRNAME is CHARACTER*(*). It's the name of the routine which called XERBLA. 🎀
  • INFO — INFO is INTEGER. It's the position of the invalid parameter in the parameter list of the calling routine. 🔥
