💖 TESTING/LIN/ddrvpo.f(3) 💖

okay bestie, this one comes straight outta the Library Functions Manual, and it's all about ddrvpo — no cap, it's giving “test-driver subroutine” energy with a full parameter list. 🎀

✨ NAME ✨

TESTING/LIN/ddrvpo.f

that's the name, bestie — don't wear it out 💅

---

🌸 SYNOPSIS 🌸

🫶 Functions/Subroutines

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

---

🦋 Function/Subroutine Documentation 🦋

here's the full typed-out signature, bestie — yes, every dimension and type is staying exactly where it belongs:

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)
    DDRVPO

🎯 Purpose

okay so the whole serve is literally this: DDRVPO tests the driver routines DPOSV and -SVX. periodt. 💅

🧚 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 side vectors to be generated for each linear system.
• 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.
• NMAX — INTEGER. The maximum value permitted for N, used in dimensioning the work arrays.
• 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)).
• RWORK — DOUBLE PRECISION array, dimension (NMAX+2*NRHS).
• IWORK — INTEGER array, dimension (NMAX).
• NOUT — INTEGER. The unit number for output.
