TESTING/LIN/ddrvge.f(3)

💖 NAME 💖

okay so bestie, this page is for TESTING/LIN/ddrvge.f — from the Library Functions Manual — and that’s the whole name section, no cap. 🎀

✨ SYNOPSIS ✨

🦋 Functions/Subroutines 🦋

subroutine ddrvge (dotype, nn, nval, nrhs, thresh, tsterr, nmax, a,
     afac, asav, b, bsav, x, xact, s, work, rwork, iwork, nout)

DDRVGE — main character subroutine energy, literally. 💅

🌸 subroutine ddrvge

Here’s the full typed-out signature, exactly as it appears:

   subroutine ddrvge (logical, dimension( * ) dotype, integer nn, integer,
       dimension( * ) nval, integer nrhs, double precision thresh, logical
       tsterr, integer nmax, double precision, dimension( * ) a, double
       precision, dimension( * ) afac, double precision, dimension( * ) asav,
       double precision, dimension( * ) b, double precision, dimension( * )
       bsav, double precision, dimension( * ) x, double precision, dimension( *
       ) xact, double precision, dimension( * ) s, double precision, dimension(
       * ) work, double precision, dimension( * ) rwork, integer, dimension( *
       ) iwork, integer nout)

Also the name is DDRVGE, and yes, it ate. ✨

🎯 Purpose 🎯

DDRVGE tests the driver routines DGESV and -SVX.

That’s the purpose, bestie. It’s a test driver checking those routines. Periodt. 💖

📋 Parameters 📋

• DOTYPE — DOTYPE is LOGICAL array, dimension (NTYPES). These are 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. It’s the number of values of N contained in the vector NVAL.
• NVAL — NVAL is INTEGER array, dimension (NN). These are the values of the matrix column 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 DOUBLE PRECISION array, dimension (NMAX*NMAX).
• AFAC — AFAC is DOUBLE PRECISION array, dimension (NMAX*NMAX).
• ASAV — ASAV is DOUBLE PRECISION array, dimension (NMAX*NMAX).
• B — B is DOUBLE PRECISION array, dimension (NMAX*NRHS).
• BSAV — BSAV is DOUBLE PRECISION array, dimension (NMAX*NRHS).
• X — X is DOUBLE PRECISION array, dimension (NMAX*NRHS).
• XACT — XACT is DOUBLE PRECISION array, dimension (NMAX*NRHS).
• S — S is DOUBLE PRECISION array, dimension (2*NMAX).
• WORK — WORK is DOUBLE PRECISION array, dimension (NMAX*max(3,NRHS)).
• RWORK — RWORK is DOUBLE PRECISION array, dimension (2*NRHS+NMAX).
• IWORK — IWORK is INTEGER array, dimension (2*NMAX).
• NOUT — NOUT is INTEGER. The unit number for output.

Cute sign-off, bestie: this footer is giving LAPACK Version 3.12.0 and page TESTING/LIN/ddrvge.f(3) — the date field is literally blank in the source, so we’re not inventing one. Keeping it factual and cute. 🫶💅
