💅 TESTING/EIG/schkbl.f (the page, but make it cute)

okay bestie, so this is the manual page for TESTING/EIG/schkbl.f ✨ it lives in the LAPACK library functions manual and it's short, sweet, and honestly a whole vibe. let's get into it 🎀

🌸 NAME 🌸

TESTING/EIG/schkbl.f — like, literally that. that's the name. iconic behavior tbh 💅

✨ SYNOPSIS ✨

Functions/Subroutines

  • subroutine schkbl (nin, nout) — the one and only, and yes, its whole personality is SCHKBL 🦋

🫶 Function/Subroutine Documentation 🫶

okay so here's the actual signature, character for character, no cap:

subroutine schkbl (integer nin, integer nout)

and the description block just says SCHKBL. that's it. that's the summary. she's mysterious 💜

⭐ Purpose ⭐

straight from the source, and yes i'm keeping the doc-comment marks because they're part of the lore:

!>
!> SCHKBL tests SGEBAL, a routine for balancing a general real
!> matrix and isolating some of its eigenvalues.
!>

so yeah — SCHKBL is the test routine for SGEBAL, which is the routine that balances a general real matrix and isolates some of its eigenvalues. it's giving quality-assurance main character energy 👑 lowkey important work!

🌈 Parameters 🌈

  • NIN — declared as INTEGER 💖 and fr fr, here's what the source says:
!>          NIN is INTEGER
!>          The logical unit number for input.  NIN > 0.
!>

so: the logical unit number for input, and it has to be NIN > 0. no zero, no negatives, bestie, we're not doing that 🙈

  • NOUT — also declared INTEGER 🎀 with this to say:
!>          NOUT is INTEGER
!>          The logical unit number for output.  NOUT > 0.
!>

the logical unit number for output, and yup, NOUT > 0 too. same rules, same energy 💀
