🦋 TESTING/LIN/ddrvgt.f(3) — Library Functions Manual 🦋

okay bestie, welcome to the TESTING/LIN/ddrvgt.f page from the Library Functions Manual. This is the ddrvgt corner of LAPACK, and it’s lowkey all about testing. ✨

💖 NAME 💖

TESTING/LIN/ddrvgt.f — that’s the file/page name, and the manual name is Library Functions Manual. The function doing the main-character thing here is ddrvgt. 💅

✨ SYNOPSIS ✨

🧚 Functions/Subroutines 🧚

       subroutine ddrvgt (dotype, nn, nval, nrhs, thresh, tsterr, a, af, b, x,
           xact, work, rwork, iwork, nout)
           DDRVGT

💻 Function/Subroutine Documentation 💻

   subroutine ddrvgt (logical, dimension( * ) dotype, integer nn, integer,
       dimension( * ) nval, integer nrhs, double precision thresh, logical
       tsterr, double precision, dimension( * ) a, double precision, dimension(
       * ) af, double precision, dimension( * ) b, double precision, dimension(
       * ) x, double precision, dimension( * ) xact, double precision,
       dimension( * ) work, double precision, dimension( * ) rwork, integer,
       dimension( * ) iwork, integer nout)
       DDRVGT

🎯 Purpose 🎯

DDRVGT tests DGTSV and -SVX. That’s the whole purpose, bestie — it’s giving “test those routines.” 💅

💅 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.
  • NRHS — INTEGER. The number of right hand sides, NRHS >= 0.
  • 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.
  • A — DOUBLE PRECISION array, dimension (NMAX*4).
  • AF — DOUBLE PRECISION array, dimension (NMAX*4).
  • B — DOUBLE PRECISION array, dimension (NMAX*NRHS).
  • X — DOUBLE PRECISION array, dimension (NMAX*NRHS).
  • XACT — DOUBLE PRECISION array, dimension (NMAX*NRHS).
  • WORK — DOUBLE PRECISION array, dimension (NMAX*max(3,NRHS)).
  • RWORK — DOUBLE PRECISION array, dimension (max(NMAX,2*NRHS)).
  • IWORK — INTEGER array, dimension (2*NMAX).
  • NOUT — INTEGER. The unit number for output.
