💖 NAME 💖

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

okay bestie, this is the page from the Library Functions Manual for /home/abui...khe_rook.f(3) — header folded in right here, no cap. The full NAME path is the one above, and it's giving “we test LAPACK routines and we're gonna be thorough about it” energy. 💅

✨ SYNOPSIS ✨

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

🌸 Purpose 🌸

The actual purpose, straight from the source, is this little icon:

!>
!> ZCHKHE_ROOK tests ZHETRF_ROOK, -TRI_ROOK, -TRS_ROOK,
!> and -CON_ROOK.

🎀 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.
• 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 — CCOMPLEX*16 array, dimension (NMAX*NMAX).
• AFAC — COMPLEX*16 array, dimension (NMAX*NMAX).
• AINV — COMPLEX*16 array, dimension (NMAX*NMAX).
• B — CCOMPLEX*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(NMAX,2*NSMAX) — yep, that's exactly how it appears in the source, closing-paren situation and all. I'm not fixing it, I'm preserving it. 🫶
• IWORK — INTEGER array, dimension (2*NMAX).
• NOUT — INTEGER. The unit number for output.

okay that's the whole page, bestie 🫶. The footer vibe is LAPACK Version 3.12.0 with /home/abui...khe_rook.f(3) as the source path. No date is printed on this page, so we're not inventing one. 💜✨
