💅 TESTING/EIG/cchkec.f(3) — Library Functions Manual, but make it cute 💅

okay bestie, this is the manual page for TESTING/EIG/cchkec.f, and it's literally all about the CCHKEC routine. no cap.

🌸 NAME 🌸

TESTING/EIG/cchkec.f — yep, that's the name, periodt.

✨ SYNOPSIS ✨

Functions/Subroutines

subroutine cchkec (thresh, tsterr, nin, nout)
           CCHKEC

🎀 Function/Subroutine Documentation 🎀

🧚 subroutine cchkec (real thresh, logical tsterr, integer nin, integer nout) 🧚

CCHKEC

💡 Purpose:

CCHKEC tests eigen-condition estimation routines — and the whole squad is here: 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.

🎚️ 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.
