ZCHKQL(3)

💅 ZCHKQL(3) — Library Functions Manual energy 💅

okay so bestie, this is the manual page for ZCHKQL(3) in the Library Functions Manual, and the file tag vibing at the top and footer is /home/abui...IN/zchkql.f(3). We're deep in LAPACK testing territory now, no cap. 🫶

🎀 NAME 🎀

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

That's literally the whole NAME section, bestie. It's giving "the source file is the moment." 💅

✨ SYNOPSIS ✨

🧚 Functions/Subroutines 🧚

• subroutine ZCHKQL — the main character, with this exact signature:

subroutine ZCHKQL (dotype, nm, mval, nn, nval, nnb, nbval, nxval, nrhs,
    thresh, tsterr, nmax, a, af, aq, al, ac, b, x, xact, tau, work,
    rwork, nout)

ZCHKQL is the name on the label, periodt.

🦋 Function/Subroutine Documentation 🦋

Here's the full signature exactly as the page serves it:

subroutine ZCHKQL (logical, dimension( * ) dotype, integer nm, integer,
    dimension( * ) mval, integer nn, integer, dimension( * ) nval, integer
    nnb, integer, dimension( * ) nbval, integer, dimension( * ) nxval,
    integer nrhs, double precision thresh, logical tsterr, integer nmax,
    complex*16, dimension( * ) a, complex*16, dimension( * ) af, complex*16,
    dimension( * ) aq, complex*16, dimension( * ) al, complex*16, dimension(
    * ) ac, complex*16, dimension( * ) b, complex*16, dimension( * ) x,
    complex*16, dimension( * ) xact, complex*16, dimension( * ) tau,
    complex*16, dimension( * ) work, double precision, dimension( * ) rwork,
    integer nout)

Name label: ZCHKQL. Iconic, honestly. 👑

🎯 Purpose

ZCHKQL tests ZGEQLF, ZUNGQL and ZUNMQL.

That's the whole purpose, and it ate. ✨

🌸 Parameters 🌸

• DOTYPE — DOTYPE is LOGICAL array, dimension (NTYPES). The matrix types to be used for testing. Matrices of type j (for 1 <= j <= NTYPES) are used for testing if DOTYPE(j) = .TRUE.; if DOTYPE(j) = .FALSE., then type j is not used. 🎀
• 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 and NX contained in the vectors NBVAL and NXVAL. The blocking parameters are used in pairs (NB,NX).
• NBVAL — NBVAL is INTEGER array, dimension (NNB). The values of the blocksize NB.
• NXVAL — NXVAL is INTEGER array, dimension (NNB). The values of the crossover point NX.
• NRHS — NRHS is INTEGER. The number of right hand side vectors to be generated for each linear system.
• 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.
• NMAX — NMAX is INTEGER. The maximum value permitted for M or N, used in dimensioning the work arrays.
• A — A is COMPLEX*16 array, dimension (NMAX*NMAX).
• AF — AF is COMPLEX*16 array, dimension (NMAX*NMAX).
• AQ — AQ is COMPLEX*16 array, dimension (NMAX*NMAX).
• AL — AL is COMPLEX*16 array, dimension (NMAX*NMAX).
• AC — AC is COMPLEX*16 array, dimension (NMAX*NMAX).
• B — B is COMPLEX*16 array, dimension (NMAX*NRHS).
• X — X is COMPLEX*16 array, dimension (NMAX*NRHS).
• XACT — XACT is COMPLEX*16 array, dimension (NMAX*NRHS).
• TAU — TAU is COMPLEX*16 array, dimension (NMAX).
• WORK — WORK is COMPLEX*16 array, dimension (NMAX*NMAX).
• RWORK — RWORK is DOUBLE PRECISION array, dimension (NMAX).
• NOUT — NOUT is INTEGER. The unit number for output.
