💖 TESTING/LIN/xerbla.f 💖

okay so bestie, this page is TESTING/LIN/xerbla.f(3) from the Library Functions Manual — she's a little test-suite special, and we're obsessed. 🫶

✨ NAME ✨

TESTING/LIN/xerbla.f — that's the file, periodt. 💅

🌸 SYNOPSIS 🌸

Functions/Subroutines

subroutine xerbla (srname, info)
           XERBLA

💅 Function/Subroutine Documentation 💅

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

XERBLA

🔥 Purpose 🔥

This is a special version of XERBLA that is only for the test program checking error exits from the LAPACK routines. Error messages get printed if INFO.NE.INFOT or if SRNAME.NE.SRNAMT, where INFOT and SRNAMT are values stored in COMMON. 😭✨

🍓 Parameters 🍓

  • SRNAME — SRNAME is CHARACTER*(*). It's the name of the subroutine calling XERBLA, and this name should match the COMMON variable SRNAMT. 🎀
  • INFO — INFO is INTEGER. It's the error return code from the calling subroutine, and INFO should equal the COMMON variable INFOT. 💖
