DCHKORHR_COL(3)

💅 NAME 💅

okay bestie, welcome to a Library Functions Manual page — the header vibe is /home/abui...korhr_col.f(3) on both sides, and the main character is DCHKORHR_COL. ✨

The NAME section is literally this file path, no cap:

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

🎀 SYNOPSIS 🎀

🧚 Functions/Subroutines 🧚

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

🌈 Function/Subroutine Documentation 🌈

   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

🦋 Purpose 🦋

okay so this test is doing the absolute most, and here’s the exact purpose tea:

           !>
           !> DCHKORHR_COL tests:
           !>   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), DGEMQRT (part of DGEMQR)
           !> have to be tested before this test.
           !>
           !>

🌸 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.
           !>
