💖 NAME 💖

TESTING/LIN/sdrvsy_rook.f — this is the SDRVSY_ROOK test-driver page, bestie. It lives in the Library Functions Manual under the page name TESTING/LI...rvsy_rook.f(3). We are so back.

🛠️ Function/Subroutine Documentation 🛠️

   subroutine sdrvsy_rook (logical, dimension( * ) dotype, integer nn, integer,
       dimension( * ) nval, integer nrhs, 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)
       SDRVSY_ROOK

🎯 Purpose 🎯

The Doxygen purpose block is literally !> SDRVSY_ROOK tests the driver routines SSYSV_ROOK. !> — that's the whole vibe. It tests the driver routines SSYSV_ROOK, no cap.

🌈 Parameters 🌈

The source wraps each parameter description in !> Doxygen markers; here's the actual tea, with all the types, dimensions, and conditions kept exactly.

• DOTYPE — DOTYPE is 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 — NN is INTEGER. The number of values of N contained in the vector NVAL.
• NVAL — NVAL is INTEGER array, dimension (NN). The values of the matrix dimension N.
• NRHS — NRHS is INTEGER. The number of right hand side vectors to be generated for each linear system.
• THRESH — THRESH is 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 — TSTERR is LOGICAL. Flag that indicates whether error exits are to be tested.
• NMAX — NMAX is INTEGER. The maximum value permitted for N, used in dimensioning the work arrays.
• A — A is REAL array, dimension (NMAX*NMAX).
• AFAC — AFAC is REAL array, dimension (NMAX*NMAX).
• AINV — AINV is REAL array, dimension (NMAX*NMAX).
• B — B is REAL array, dimension (NMAX*NRHS).
• X — X is REAL array, dimension (NMAX*NRHS).
• XACT — XACT is REAL array, dimension (NMAX*NRHS).
• WORK — WORK is REAL array, dimension (NMAX*max(2,NRHS)).
• RWORK — RWORK is REAL array, dimension (NMAX+2*NRHS).
• IWORK — IWORK is INTEGER array, dimension (2*NMAX).
• NOUT — NOUT is INTEGER. The unit number for output.
