✨ NAME ✨

TESTING/LIN/sdrvgex.f — okay so bestie, this is the page for the sdrvge subroutine (and its SDRVGEX era) from the Library Functions Manual. It’s giving LAPACK testing energy, lowkey iconic.

🦋 SYNOPSIS 🦋

🎀 Functions/Subroutines 🎀

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

💅 Function/Subroutine Documentation 💅

🌸 subroutine sdrvge 🌸

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

⭐ Purpose ⭐

SDRVGE tests the driver routines SGESV, -SVX, and -SVXX. Note that this file is used only when the XBLAS are available, otherwise sdrvge.f defines this subroutine.

🍓 Parameters 🍓

  • DOTYPE — DOTYPE is LOGICAL array, dimension (NTYPES). It’s the matrix-type lineup: 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 column 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).
  • ASAV — ASAV is REAL array, dimension (NMAX*NMAX).
  • B — B is REAL array, dimension (NMAX*NRHS).
  • BSAV — BSAV is REAL array, dimension (NMAX*NRHS).
  • X — X is REAL array, dimension (NMAX*NRHS).
  • XACT — XACT is REAL array, dimension (NMAX*NRHS).
  • S — S is REAL array, dimension (2*NMAX).
  • WORK — WORK is REAL array, dimension (NMAX*max(3,NRHS)).
  • RWORK — RWORK is REAL array, dimension (2*NRHS+NMAX).
  • IWORK — IWORK is INTEGER array, dimension (2*NMAX).
  • NOUT — NOUT is INTEGER. The unit number for output.
