💅 TESTING/LIN/schklq.f(3) 💅

okay so bestie, you found the Library Functions Manual page for TESTING/LIN/schklq.f. It's giving LAPACK test-routine main character energy, and we are keeping every single detail. No cap. ✨

🌸 NAME 🌸

TESTING/LIN/schklq.f — yes, that's the name, and it's iconic. 💖

✨ SYNOPSIS ✨

🎀 Functions/Subroutines 🎀

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

💖 Function/Subroutine Documentation 💖

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

SCHKLQ — the subroutine itself, lowkey the whole point, and honestly? Main character energy fr fr. 👑

🎀 Purpose 🎀

SCHKLQ tests SGELQF, SORGLQ and SORMLQ. That's the purpose, and the vibe check passed. 💅

🧚 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. Obsessed with this logic.
• 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 REAL. 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 REAL array, dimension (NMAX*NMAX).
• AF — AF is REAL array, dimension (NMAX*NMAX).
• AQ — AQ is REAL array, dimension (NMAX*NMAX).
• AL — AL is REAL array, dimension (NMAX*NMAX).
• AC — AC is REAL array, dimension (NMAX*NMAX).
• B — B is REAL array, dimension (NMAX*NRHS).
• X — X is REAL array, dimension (NMAX*NRHS).
• XACT — XACT is REAL array, dimension (NMAX*NRHS).
• TAU — TAU is REAL array, dimension (NMAX).
• WORK — WORK is REAL array, dimension (NMAX*NMAX).
• RWORK — RWORK is REAL array, dimension (NMAX).
• NOUT — NOUT is INTEGER. The unit number for output.
