ZCHKPO(3)

💖 NAME 💖

Okay so this is the ZCHKPO(3) page from the Library Functions Manual, and the actual file it's documenting is literally:

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

No cap, that's the whole path. 💅

✨ SYNOPSIS ✨

🫶 Functions/Subroutines 🫶

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

🎀 subroutine ZCHKPO 🎀

Here's the full typed-out signature, bestie — exactly as the page gives it:

subroutine ZCHKPO (logical, dimension( * ) dotype, 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 nout)
       ZCHKPO

💅 Purpose 💅

ZCHKPO tests ZPOTRF, -TRI, -TRS, -RFS, and -CON

That's the whole vibe: it's the testing routine for those five. ✨

🌈 Parameters 🌈

Tiny source note: every parameter blurb below shows up in the original wrapped in !> Doxygen markers. I kept all the facts and spared you the repeated !> spam. 🫶

• DOTYPE — a LOGICAL array, dimension (NTYPES). It's the matrix-type menu: matrices of type j (for 1 <= j <= NTYPES) get used for testing if DOTYPE(j) = .TRUE.; if DOTYPE(j) = .FALSE., then type j is not used.
• NN — INTEGER. The number of values of N contained in the vector NVAL.
• NVAL — INTEGER array, dimension (NN). The values of the matrix 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.
• TSTERR — LOGICAL. Flag that indicates whether error exits are to be tested.
• NMAX — INTEGER. The maximum value permitted for 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 (NMAX+2*NSMAX).
• NOUT — INTEGER. The unit number for output.
