💅 DLCTES(3) — Library Functions Manual 💅

okay so welcome to the DLCTES(3) page, bestie. It's giving Library Functions Manual energy, and the header has that iconic truncated path: /home/abui...IG/dlctes.f(3). The actual source file is doing main-character things down below. ✨

🌸 NAME 🌸

The NAME is literally this path, no cap:

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

✨ SYNOPSIS ✨

Functions/Subroutines

logical function DLCTES (zr, zi, d)
    DLCTES

🎀 Function/Subroutine Documentation 🎀

Here's the full signature, exactly as the original flexes it:

logical function DLCTES (double precision zr, double precision zi, double precision d)
    DLCTES

💖 Purpose 💖

DLCTES returns .TRUE. if the eigenvalue (ZR/D) + sqrt(-1)*(ZI/D) is to be selected — specifically, in this subroutine, if the real part of the eigenvalue is negative — and otherwise it returns .FALSE..

It's used by the test routine DDRGES to test whether the driver routine DGGES successfully sorts eigenvalues. eigenvalue-sorting vibe check, honestly. 🔥

🦋 Parameters 🦋

🌟 ZR 🌟

ZR is DOUBLE PRECISION. It's the numerator of the real part of a complex eigenvalue (ZR/D) + i*(ZI/D).

🌟 ZI 🌟

ZI is DOUBLE PRECISION. It's the numerator of the imaginary part of a complex eigenvalue (ZR/D) + i*(ZI).

🌟 D 🌟

D is DOUBLE PRECISION. It's the denominator part of a complex eigenvalue (ZR/D) + i*(ZI/D).

okay that's the whole page, bestie 💖. The footer energy is LAPACK Version 3.12.0, with that iconic truncated source path /home/abui...IG/dlctes.f(3). The footer doesn't print a date — just version and path — so consider this your cute little sign-off. 🫶✨
