🦋 TESTING/LIN/zchkge.f(3) — Library Functions Manual 🦋

okay so this page is giving very specific LAPACK testing energy, and the manual name is Library Functions Manual. No cap, we're getting into it.

🌸 NAME

• TESTING/LIN/zchkge.f — that's the file, bestie. Main character file behavior only.

🌈 SYNOPSIS

Functions/Subroutines

subroutine zchkge (dotype, nm, mval, nn, nval, nnb, nbval, nns, nsval,
    thresh, tsterr, nmax, a, afac, ainv, b, x, xact, work, rwork, iwork,
    nout)

ZCHKGE — yes, that's the star of the show, periodt.

🎯 Purpose

ZCHKGE tests ZGETRF, -TRI, -TRS, -RFS, and -CON. That's the whole purpose, and it ate.

💅 Parameters

• DOTYPE — 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 — INTEGER. The number of values of M contained in the vector MVAL.
• MVAL — INTEGER array, dimension (NM). The values of the matrix row dimension M.
• NN — INTEGER. The number of values of N contained in the vector NVAL.
• NVAL — INTEGER array, dimension (NN). The values of the matrix column dimension N.
• NNB — INTEGER. The number of values of NB contained in the vector NBVAL.
• NBVAL — INTEGER array, dimension (NNB). The values of the blocksize NB.
• NNS — INTEGER. The number of values of NRHS contained in the vector NSVAL.
• NSVAL — INTEGER array, dimension (NNS). The values of the number of right hand sides NRHS.
• THRESH — 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. Every. Single. One. 💅

• TSTERR — LOGICAL. Flag that indicates whether error exits are to be tested.
• NMAX — INTEGER. The maximum value permitted for M or N, used in dimensioning the work arrays.
• A — COMPLEX*16 array, dimension (NMAX*NMAX).
• AFAC — COMPLEX*16 array, dimension (NMAX*NMAX).
• AINV — COMPLEX*16 array, dimension (NMAX*NMAX).
• B — COMPLEX*16 array, dimension (NMAX*NSMAX) where NSMAX is the largest entry in NSVAL.
• X — COMPLEX*16 array, dimension (NMAX*NSMAX).
• XACT — COMPLEX*16 array, dimension (NMAX*NSMAX).
• WORK — COMPLEX*16 array, dimension (NMAX*max(3,NSMAX)).
• RWORK — DOUBLE PRECISION array, dimension (max(2*NMAX,2*NSMAX+NWORK)).
• IWORK — INTEGER array, dimension (NMAX).
• NOUT — INTEGER. The unit number for output.
