TESTING/LI...unhr_col.f(3)

Welcome to the TESTING/LI...unhr_col.f(3) page from the LAPACK Library Functions Manual — yes bestie, that's the manual name folded right in at the top. Buckle up, we're doing Fortran testing tea. 💖

🌸 NAME 🌸

The name is literally TESTING/LIN/cchkunhr_col.f — that's the file, that's the vibe. 🎀

✨ SYNOPSIS ✨

Under Functions/Subroutines, you get this little icon:

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

🎀 Function/Subroutine Documentation 🎀

Here's the full signature, no cap:

   subroutine cchkunhr_col (real thresh, logical tsterr, integer nm, integer,
       dimension( * ) mval, integer nn, integer, dimension( * ) nval, integer
       nnb, integer, dimension( * ) nbval, integer nout)
       CCHKUNHR_COL

CCHKUNHR_COL is the main character here. 👑

🔥 Purpose 🔥

Okay so the way that CCHKUNHR_COL tests things is:

1. CUNGTSQR and CUNHR_COL using CLATSQR, CGEMQRT.
2. CUNGTSQR_ROW and CUNHR_COL inside CGETSQRHRT (which calls CLATSQR, CUNGTSQR_ROW and CUNHR_COL) using CGEMQRT.

So therefore, CLATSQR (part of CGEQR) and CGEMQRT (part of CGEMQR) have to be tested before this test. That's not optional, bestie — it's giving prerequisite energy. 💅

🧪 Parameters 🧪

THRESH

THRESH is REAL. It's 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 — periodt. ✨

TSTERR

TSTERR is LOGICAL. This flag 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. 🙈
