ZCHKUNHR_COL(3)

💖 ZCHKUNHR_COL(3) 💖

Okay bestie, welcome to zchkunhr_col.f(3) from the Library Functions Manual — this is the test-driver page for ZCHKUNHR_COL, and we're keeping every detail because that's the whole point. ✨

🎀 NAME 🎀

/home/abuild/rpmbuild/BUILD/lapack-static-3.12.0-build/lapack-3.12.0/TESTING/LIN/zchkunhr_col.f

✨ SYNOPSIS ✨

🌸 Functions/Subroutines 🌸

subroutine ZCHKUNHR_COL (thresh, tsterr, nm, mval, nn, nval, nnb, nbval,
    nout)
    ZCHKUNHR_COL

🦋 Function/Subroutine Documentation 🦋

Here's the full typed-out signature, bestie — every type and every dimension( * ) is staying:

subroutine ZCHKUNHR_COL (double precision thresh, logical tsterr, integer
    nm, integer, dimension( * ) mval, integer nn, integer, dimension( * )
    nval, integer nnb, integer, dimension( * ) nbval, integer nout)
    ZCHKUNHR_COL

🌸 Purpose 🌸

ZCHKUNHR_COL is the test for these two flavors:

1. ZUNGTSQR and ZUNHR_COL using ZLATSQR, ZGEMQRT,
2. ZUNGTSQR_ROW and ZUNHR_COL inside ZGETSQRHRT (which calls ZLATSQR, ZUNGTSQR_ROW and ZUNHR_COL) using ZGEMQRT.

So literally, ZLATSQR (part of ZGEQR) and ZGEMQRT (part of ZGEMQR) have to be tested before this test. No skipping, no cap. 💅

Order matters, bestie — those prerequisites have to be tested before this one.

💅 Parameters 💅

• THRESH — THRESH is DOUBLE PRECISION. The threshold value for the test ratios. A result is included in the output file if RESULT >= THRESH. To have every test ratio printed, use THRESH = 0.
• TSTERR — TSTERR is LOGICAL. Flag that indicates whether error exits are to be tested.
• NM — NM is INTEGER. The number of values of M contained in the vector MVAL.
• MVAL — MVAL is INTEGER array, dimension (NM). The values of the matrix row dimension M.
• NN — NN is INTEGER. The number of values of N contained in the vector NVAL.
• NVAL — NVAL is INTEGER array, dimension (NN). The values of the matrix column dimension N.
• NNB — NNB is INTEGER. The number of values of NB contained in the vector NBVAL.
• NBVAL — NBVAL is INTEGER array, dimension (NNB). The values of the blocksize NB.
• NOUT — NOUT is INTEGER. The unit number for output.
