SDRVSY(3)

okay bestie, welcome to the sdrvsy.f(3) page from the Library Functions Manual 💖✨ This one is a LAPACK testing subroutine and it’s giving “I test driver routines” energy, no cap.

🎀 NAME 🎀

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

✨ SYNOPSIS ✨

💖 Functions/Subroutines 💖

The callable icon is:

       subroutine SDRVSY (dotype, nn, nval, nrhs, thresh, tsterr, nmax, a,
           afac, ainv, b, x, xact, work, rwork, iwork, nout)
           SDRVSY

📖 Function/Subroutine Documentation 📖

Full signature, no cap:

   subroutine SDRVSY (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

🌸 Purpose 🌸

SDRVSY tests the driver routines SSYSV and -SVX. That’s the whole mood fr fr 💅

💅 Parameters 💅

• 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 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 — 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.
