okay bestie, welcome to the TESTING/LI...unhr_col.f(3) page from the Library Functions Manual — it’s giving major testing energy for TESTING/LIN/zchkunhr_col.f. 💅✨

🌸 NAME 🌸

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 🦋

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 main character here, and it tests:

  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.

Therefore, ZLATSQR (part of ZGEQR), ZGEMQRT (part of ZGEMQR) have to be tested before this test. like, no cap, those prerequisites are literally not optional. 💀🔥

🧸 Parameters 🧸

  • THRESH — THRESH is DOUBLE PRECISION. 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. 🔥
  • 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.
