TESTING/LIN/zchksy.f(3)

okay so this is TESTING/LIN/zchksy.f(3), straight outta the LAPACK Library Functions Manual, and we're about to vibe-check zchksy together. no cap, it's giving iconic LAPACK testing energy and I'm obsessed. 🦋💖

💅 NAME 💅

TESTING/LIN/zchksy.f — that's the file, bestie. periodt.

✨ SYNOPSIS ✨

🎀 Functions/Subroutines 🎀

• subroutine zchksy — the whole squad of args is right here:

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

ZCHKSY — yes, that's the subroutine name, main character energy only. 👑

🦋 Function/Subroutine Documentation 🦋

   subroutine zchksy (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, dimension( * ) iwork, integer nout)

ZCHKSY — okay bestie, this is the function/subroutine we're documenting. 💖

🌸 Purpose 🌸

ZCHKSY tests ZSYTRF, -TRI2, -TRS, -TRS2, -RFS, and -CON.

🎀 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 — 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(2,NSMAX)).
• RWORK — DOUBLE PRECISION array, dimension (NMAX+2*NSMAX).
• IWORK — INTEGER array, dimension (NMAX).
• NOUT — INTEGER. The unit number for output.
