SCHKEC(3)

💖 NAME 💖

okay bestie, this is schkec.f(3), straight out of the Library Functions Manual — and the file it's repping is this absolute path:

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

---

✨ SYNOPSIS ✨

🎀 Functions/Subroutines 🎀

here's the callable cutie:

subroutine SCHKEC (thresh, tsterr, nin, nout)
    SCHKEC

---

🌸 Function/Subroutine Documentation 🌸

subroutine SCHKEC (real thresh, logical tsterr, integer nin, integer nout)
    SCHKEC

💅 Purpose

no cap, this is the whole point: SCHKEC tests eigen-condition estimation routines — specifically these iconic ones:

SLALN2, SLASY2, SLANV2, SLAQTR, SLAEXC, STRSYL, STREXC, STRSNA, STRSEN, STGEXC

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, STREXC, STRSNA and STRSEN 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. 🌈
