SCHKSY_ROOK.F(3)

🌈 NAME 🌈

okay bestie, this is the page for TESTING/LIN/schksy_rook.f, and the manual-page name we’re folding in right up top is TESTING/LI...hksy_rook.f(3). It’s giving LAPACK testing energy, fr fr. 💅

✨ SYNOPSIS ✨

🧚 Functions/Subroutines 🧚

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

💖 Function/Subroutine Documentation 💖

   subroutine schksy_rook (logical, dimension( * ) dotype, integer nn, integer,
       dimension( * ) nval, integer nnb, integer, dimension( * ) nbval, integer
       nns, integer, dimension( * ) nsval, real thresh, logical tsterr, integer
       nmax, real, dimension( * ) a, real, dimension( * ) afac, real,
       dimension( * ) ainv, real, dimension( * ) b, real, dimension( * ) x,
       real, dimension( * ) xact, real, dimension( * ) work, real, dimension( *
       ) rwork, integer, dimension( * ) iwork, integer nout)
       SCHKSY_ROOK

🎀 Purpose 🎀

okay so the whole point: SCHKSY_ROOK tests SSYTRF_ROOK, -TRI_ROOK, -TRS_ROOK, and -CON_ROOK. No cap, that’s the vibe. ✨

🌸 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 — REAL. 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 — REAL array, dimension (NMAX*NMAX).
• AFAC — REAL array, dimension (NMAX*NMAX).
• AINV — REAL array, dimension (NMAX*NMAX).
• B — REAL array, dimension (NMAX*NSMAX) where NSMAX is the largest entry in NSVAL.
• X — REAL array, dimension (NMAX*NSMAX).
• XACT — REAL array, dimension (NMAX*NSMAX).
• WORK — REAL array, dimension (NMAX*max(3,NSMAX)).
• RWORK — REAL array, dimension (max(NMAX,2*NSMAX)).
• IWORK — INTEGER array, dimension (2*NMAX).
• NOUT — INTEGER. The unit number for output.
