ZLCTES(3)

📦 version 3.12.0, in opensuse-leap 16.0

💅 ZLCTES(3) — the man page, but make it make sense ✨

okay bestie, so this is ZLCTES(3), a Library Functions Manual situation, and it lives at /home/abui...IG/zlctes.f(3) — that's literally where the page header points, no cap 🫶. grab a lil snack, we're learning a Fortran logical function. it's giving "niche but iconic" 💖

🌸 NAME 🌸

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

that's the whole name. yes, the entire path IS the name, she's extra like that 💅 and honestly? respect.

✨ SYNOPSIS ✨

🦋 Functions/Subroutines 🦋

  • logical function ZLCTES (z, d) — the whole vibe, right here
    • ZLCTES — and that's the description. she contains multitudes 💀

🎀 Function/Subroutine Documentation 🎀

⭐ the signature, the moment, the main character ⭐

logical function ZLCTES (complex*16 z, complex*16 d)

ZLCTES

💜 Purpose:

ZLCTES returns .TRUE. if the eigenvalue Z/D is to be selected — and in this subroutine specifically, that means if the real part of the eigenvalue is negative — and otherwise it returns .FALSE. 👑

it's literally used by the test routine ZDRGES to test whether the driver routine ZGGES successfully sorts eigenvalues. so like, she's the vibe check for eigenvalue sorting. the bouncer at the club. the "you may enter 💅" of linear algebra. no cap 🌈

🍓 Parameters

  • Z — Z is COMPLEX*16, and it's the numerator part of a complex eigenvalue Z/D 🌸
  • D — D is COMPLEX*16, and it's the denominator part of a complex eigenvalue Z/D 🦋

so together they're Z/D, the eigenvalue. numerator bestie and denominator bestie, two halves of one iconic whole 💖

⚠️ little note bestie: nothing here is deprecated or dangerous, she's just a humble logical function doing her one job. but you DO need both Z and D as COMPLEX*16 — do not come in here with reals, i'm begging 🙈

and that's the whole page, periodt 🎀

this cutie was brought to you by LAPACK, Version 3.12.0, dated right there in the footer alongside /home/abui...IG/zlctes.f(3) — mwah, bye bestie 💜🫶
