CCHKEC(3)

📦 version 3.12.0, in opensuse-leap 16.0

CCHKEC(3) — Library Functions Manual! Okay bestie, this is the vibe check for a LAPACK test routine, and yes we are reading the whole thing. 💅✨

💖 NAME 💖

/home/abui...IG/cchkec.f — that’s the file path this page is repping. No cap. 🫶

✨ SYNOPSIS ✨

🌸 Functions/Subroutines 🌸

  • subroutine CCHKEC (thresh, tsterr, nin, nout) — CCHKEC

🌈 Function/Subroutine Documentation 🌈

🌟 subroutine CCHKEC (real thresh, logical tsterr, integer nin, integer nout) 🌟

CCHKEC — iconic. 👑

🦋 Purpose 🦋

Okay so CCHKEC tests eigen-condition estimation routines: CTRSYL, CTRSYL3, CTREXC, CTRSNA, CTRSEN. 💜

In all cases, the routine runs through a fixed set of numerical examples, subjects them to various tests, and compares the test results to a threshold THRESH. In addition, CTRSNA and CTRSEN are tested by reading in precomputed examples from a file (on input unit NIN). Output is written to output unit NOUT. Literally all the deets. 🔥

🍓 Parameters 🍓

  • THRESH — THRESH is REAL. Threshold for residual tests. A computed test ratio passes the threshold if it is less than THRESH. 💖
  • TSTERR — TSTERR is LOGICAL. Flag that indicates whether error exits are to be tested. ✨
  • NIN — NIN is INTEGER. The logical unit number for input. 🎀
  • NOUT — NOUT is INTEGER. The logical unit number for output. 🦋
