TESTING/EIG/clctes.f(3)

Hey bestie 💖 welcome to the glow-up of TESTING/EIG/clctes.f(3) from the Library Functions Manual. We’re about to make a tiny Fortran function feel fully iconic. ✨

💖 NAME 💖

TESTING/EIG/clctes.f — that’s the file we’re stanning today, and it’s where CLCTES lives. Yes bestie, we’re reading the whole thing together. 💅

✨ SYNOPSIS ✨

🦋 Functions/Subroutines 🦋

logical function clctes (z, d)
    CLCTES

Short, sweet, and to the point — like a good group-chat voice note. 🎀

👑 Function/Subroutine Documentation 👑

logical function clctes (complex z, complex d)

CLCTES

Okay so this is the actual function doc. CLCTES is a logical function, and the two arguments are complex z and complex d. Let’s get into it. 🌸

🌸 Purpose 🌸

CLCTES returns .TRUE. if the eigenvalue Z/D is to be selected — specifically, in this subroutine, if the real part of the eigenvalue is negative — and otherwise it returns .FALSE.. That’s the whole vibe check. 💖

Here’s the tea: it’s used by the test routine CDRGES to test whether the driver routine CGGES successfully sorts eigenvalues. No cap, that’s literally its job. 🫶

🍓 Parameters 🍓

Z

Z is COMPLEX — the numerator part of a complex eigenvalue Z/D. 💅

D

D is COMPLEX — the denominator part of a complex eigenvalue Z/D. 💅

Catch you later, bestie 🌈 — source/version is LAPACK, Version 3.12.0, footer tag is TESTING/EIG/clctes.f(3), and the date is not shown on the original footer, so I’m not inventing one. Periodt. 💀✨
