DCHKBK(3)

💖 DCHKBK(3) — Library Functions Manual, but make it cute 💖

Ok so DCHKBK(3) is a Library Functions Manual page for a LAPACK testing subroutine, and it’s honestly giving “I test the tester” energy. The full file path has main character build-directory vibes, and it’s coming up in NAME. 🫶

📛 NAME

/home/abuild/rpmbuild/BUILD/lapack-static-3.12.0-build/lapack-3.12.0/TESTING/EIG/dchkbk.f

That is the file this page is about. No cap, not a drill — that whole path is the name. 💅

🌸 SYNOPSIS

Functions/Subroutines

• subroutine DCHKBK (nin, nout) — the subroutine, with its two args.
• DCHKBK — just the name again, slaying quietly.

🧚 Function/Subroutine Documentation

subroutine DCHKBK (integer nin, integer nout)

DCHKBK

Ok bestie, here’s the whole function-doc moment. DCHKBK is the subroutine, and the signatures above are exactly what you’re working with.

🎯 Purpose

DCHKBK tests DGEBAK, a routine for backward transformation of the computed right or left eigenvectors if the original matrix was preprocessed by balance subroutine DGEBAL.

That’s the whole point: it’s checking DGEBAK’s behavior, not out here doing random side quests. ✨

🧪 Parameters

NIN

NIN is INTEGER — the logical unit number for input. NIN > 0.

NOUT

NOUT is INTEGER — the logical unit number for output. NOUT > 0.

Final sign-off, bestie: source/version is LAPACK, Version 3.12.0, and the footer path is /home/abui...IG/dchkbk.f(3). The original footer doesn’t show a date, so I’m not inventing one — no fake timestamp energy. 💖🦋✨
