🎀 TESTING/LIN/ddrvpox.f 🎀

okay so bestie, this is the Library Functions Manual page for TESTING/LIN/ddrvpox.f, and it is lowkey iconic in the most Fortran-testing way possible. 💅

🌸 NAME 🌸

TESTING/LIN/ddrvpox.f — yes, that’s the name, and we’re obsessed. 🫶

✨ SYNOPSIS ✨

🦋 Functions/Subroutines 🦋

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

🔥 Function/Subroutine Documentation 🔥

okay here’s the full signature, bestie — look at all those arguments, it’s giving main character energy:

subroutine ddrvpo (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)
       DDRVPOX

💖 Purpose 💖

DDRVPO tests the driver routines DPOSV, -SVX, and -SVXX. That’s the whole assignment, and it ate. 💅

💡 also important: this file is used only when the XBLAS are available, otherwise ddrvpo.f defines this subroutine. iykyk.

🧚 Parameters 🧚

  • DOTYPE — 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. no cap, that’s the rule. 🦋
  • NN — INTEGER. The number of values of N contained in the vector NVAL. slay.
  • NVAL — INTEGER array, dimension (NN). The values of the matrix dimension N. iconic.
  • NRHS — INTEGER. The number of right hand side vectors to be generated for each linear system. periodt.
  • 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. yes bestie, zero means show me everything. 🔥
  • TSTERR — LOGICAL. Flag that indicates whether error exits are to be tested. vibe check for error paths. 🫶
  • NMAX — INTEGER. The maximum value permitted for N, used in dimensioning the work arrays. big main character number.
  • A — DOUBLE PRECISION array, dimension (NMAX*NMAX). 💜
  • AFAC — DOUBLE PRECISION array, dimension (NMAX*NMAX). 💜
  • ASAV — DOUBLE PRECISION array, dimension (NMAX*NMAX). 💜
  • B — DOUBLE PRECISION array, dimension (NMAX*NRHS). 🍓
  • BSAV — DOUBLE PRECISION array, dimension (NMAX*NRHS). 🍓
  • X — DOUBLE PRECISION array, dimension (NMAX*NRHS). 🍓
  • XACT — DOUBLE PRECISION array, dimension (NMAX*NRHS). 🍓
  • S — DOUBLE PRECISION array, dimension (NMAX). 🌸
  • WORK — DOUBLE PRECISION array, dimension (NMAX*max(3,NRHS)). literally the workspace era. ✨
  • RWORK — DOUBLE PRECISION array, dimension (NMAX+2*NRHS). ✨
  • IWORK — INTEGER array, dimension (NMAX). 🌈
  • NOUT — INTEGER. The unit number for output. that’s where the receipts go. 💅
