💅 TESTING/LI...orhr_col.f(3) — Library Functions Manual, bestie ✨

okay so this is the Library Functions Manual page for a LAPACK testing file, and it’s giving “deeply specific Fortran business.” We’re keeping every single detail, no cap. 💖

🌸 NAME 🌸

TESTING/LIN/dchkorhr_col.f

that’s the whole name. iconic. 💅

✨ SYNOPSIS ✨

🫶 Functions/Subroutines 🫶

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

the subroutine is dchkorhr_col, and the uppercase label is DCHKORHR_COL. slay. 👑

🌈 Function/Subroutine Documentation 🌈

🎀 subroutine dchkorhr_col 🎀

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

full signature, bestie — keep those types and dimensions exactly as written. 🫶

🦋 Purpose 🦋

okay so DCHKORHR_COL tests these things:

  1. DORGTSQR and DORHR_COL using DLATSQR, DGEMQRT,
  2. DORGTSQR_ROW and DORHR_COL inside DGETSQRHRT (which calls DLATSQR, DORGTSQR_ROW and DORHR_COL) using DGEMQRT.
therefore, DLATSQR (part of DGEQR) and DGEMQRT (part of DGEMQR) have to be tested before this test. don’t skip that, bestie — it’s literally in the source. 😭

🍓 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.
