DCHKGE(3)

💅 DCHKGE(3) — Library Functions Manual, but make it cute 💅

okay so you're on the DCHKGE(3) page of the Library Functions Manual, and it's literally all about the LAPACK testing routine DCHKGE, bestie. Let's get into it 💖

✨ NAME ✨

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

That's the file this whole page is serving, periodt.

🎯 Purpose 🎯

DCHKGE tests DGETRF, -TRI, -TRS, -RFS, and -CON. That's the whole vibe check for this tester 🔥

🧾 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. slay, selective testing 💅
• 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. no cap, that's how you get the full tea 🍓
• 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 — DOUBLE PRECISION array, dimension (NMAX*NMAX).
• AFAC — DOUBLE PRECISION array, dimension (NMAX*NMAX).
• AINV — DOUBLE PRECISION array, dimension (NMAX*NMAX).
• B — DOUBLE PRECISION array, dimension (NMAX*NSMAX) where NSMAX is the largest entry in NSVAL.
• X — DOUBLE PRECISION array, dimension (NMAX*NSMAX).
• XACT — DOUBLE PRECISION array, dimension (NMAX*NSMAX).
• WORK — DOUBLE PRECISION array, dimension (NMAX*max(3,NSMAX)).
• RWORK — DOUBLE PRECISION array, dimension (max(2*NMAX,2*NSMAX+NWORK)).
• IWORK — INTEGER array, dimension (2*NMAX).
• NOUT — INTEGER. The unit number for output. that's where the receipts go 🧾✨

okay bestie, that's the whole page — the footer says LAPACK Version 3.12.0 and /home/abui...IN/dchkge.f(3). bye, ily, go test those matrices 💖✨🦋
