TESTING/LIN/zchktr.f(3)

✨ NAME ✨

okay bestie, welcome to the TESTING/LIN/zchktr.f(3) page from the Library Functions Manual — it’s giving LAPACK test-routine main character energy 💅

TESTING/LIN/zchktr.f — that’s the name, and yes, it’s literally that. 🫶

🦋 SYNOPSIS 🦋

🧚 Functions/Subroutines 🧚

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

ZCHKTR — that’s the subroutine, bestie. ✨

ZCHKTR

🎀 Purpose 🎀

ZCHKTR tests ZTRTRI, -TRS, -RFS, and -CON, and ZLATRS(3). 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. 🫶
• 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 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 leading dimension of the work arrays. NMAX >= the maximum value of N in NVAL.
• A — A is COMPLEX*16 array, dimension (NMAX*NMAX).
• AINV — AINV is COMPLEX*16 array, dimension (NMAX*NMAX).
• B — B is COMPLEX*16 array, dimension (NMAX*NSMAX) where NSMAX is the largest entry in NSVAL.
• X — X is COMPLEX*16 array, dimension (NMAX*NSMAX).
• XACT — XACT is COMPLEX*16 array, dimension (NMAX*NSMAX).
• WORK — WORK is COMPLEX*16 array, dimension (NMAX*max(3,NSMAX)).
• RWORK — RWORK is DOUBLE PRECISION array, dimension (max(NMAX,2*NSMAX)).
• NOUT — NOUT is INTEGER. The unit number for output.
