ZCHKGE(3)

okay so bestie, welcome to ZCHKGE(3) — this is from the Library Functions Manual, and yes I folded the manual name in right here because we're cute and organized like that. 💅✨

🌸 NAME 🌸

The name line is literally this source path, no cap:

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

✨ SYNOPSIS ✨

🫶 Functions/Subroutines 🫶

Okay so the synopsis is giving function signature realness:

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

And then the name again, because yes:

ZCHKGE

💖 Function/Subroutine Documentation 💖

Here's the full typed-up signature, bestie — every type and dimension exactly where it belongs:

subroutine ZCHKGE (logical, dimension( * ) dotype, integer nm, integer, dimension( * ) mval, integer nn, integer, dimension( * ) nval, integer nnb, integer, dimension( * ) nbval, integer nns, integer, dimension( * ) nsval, double precision thresh, logical tsterr, integer nmax, complex*16, dimension( * ) a, complex*16, dimension( * ) afac, complex*16, dimension( * ) ainv, complex*16, dimension( * ) b, complex*16, dimension( * ) x, complex*16, dimension( * ) xact, complex*16, dimension( * ) work, double precision, dimension( * ) rwork, integer, dimension( * ) iwork, integer nout)

🎀 Purpose 🎀

ZCHKGE tests ZGETRF, -TRI, -TRS, -RFS, and -CON. That's the purpose. Iconic. Periodt. 🔥

🌈 Parameters 🌈

Lowkey a whole parade of parameters, but we're getting through them together:

• 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 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 maximum value permitted for M or N, used in dimensioning the work arrays.
• A — A is COMPLEX*16 array, dimension (NMAX*NMAX).
• AFAC — AFAC 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(2*NMAX,2*NSMAX+NWORK)).
• IWORK — IWORK is INTEGER array, dimension (NMAX).
• NOUT — NOUT is INTEGER. The unit number for output.
