💖 Library Functions Manual: TESTING/LIN/cchktr.f 💖

okay bestie, this is the TESTING/LIN/cchktr.f page from the Library Functions Manual, and it’s lowkey giving “Fortran test-driver main character energy.” Let’s get into it 💅✨

🌸 NAME 🌸

TESTING/LIN/cchktr.f

✨ SYNOPSIS ✨

🦋 Functions/Subroutines 🦋

subroutine cchktr (dotype, nn, nval, nnb, nbval, nns, nsval, thresh,
    tsterr, nmax, a, ainv, b, x, xact, work, rwork, nout)
    CCHKTR

💅 Function/Subroutine Documentation 💅

subroutine cchktr (logical, dimension( * ) dotype, integer nn, integer,
    dimension( * ) nval, integer nnb, integer, dimension( * ) nbval, integer
    nns, integer, dimension( * ) nsval, real thresh, logical tsterr, integer
    nmax, complex, dimension( * ) a, complex, dimension( * ) ainv, complex,
    dimension( * ) b, complex, dimension( * ) x, complex, dimension( * )
    xact, complex, dimension( * ) work, real, dimension( * ) rwork, integer
    nout)
    CCHKTR

🎯 Purpose 🎯

The official purpose is literally this: CCHKTR tests CTRTRI, -TRS, -RFS, and -CON, and CLATRS(3) ✨

🌈 Parameters 🌈

• DOTYPE — DOTYPE is LOGICAL array, dimension (NTYPES). This is the matrix-type vibe check: 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 💖
• 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.
• NNS — NNS is INTEGER. The number of values of NRHS contained in the vector NSVAL.
• NSVAL — NSVAL is INTEGER array, dimension (NNS). The values of the number of right hand sides NRHS.
• 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 leading dimension of the work arrays. NMAX >= the maximum value of N in NVAL.
• A — A is COMPLEX array, dimension (NMAX*NMAX).
• AINV — AINV is COMPLEX array, dimension (NMAX*NMAX).
• B — B is COMPLEX array, dimension (NMAX*NSMAX) where NSMAX is the largest entry in NSVAL.
• X — X is COMPLEX array, dimension (NMAX*NSMAX).
• XACT — XACT is COMPLEX array, dimension (NMAX*NSMAX).
• WORK — WORK is COMPLEX array, dimension (NMAX*max(3,NSMAX)).
• RWORK — RWORK is REAL array, dimension (max(NMAX,2*NSMAX)).
• NOUT — NOUT is INTEGER. The unit number for output.
