ZDRVSY_ROOK.F(3)

✨ ZDRVSY_ROOK(3) ✨

okay so welcome to the Library Functions Manual, bestie — this is the page for TESTING/LIN/zdrvsy_rook.f, and it's giving “test driver for a complex linear solve routine” energy. no cap, we're keeping every single detail. 🫶

🌸 NAME 🌸

TESTING/LIN/zdrvsy_rook.f — that's the file this whole page is about, and yes, the ZDRVSY_ROOK subroutine lives here. 💅

✨ SYNOPSIS ✨

under Functions/Subroutines we have:

subroutine zdrvsy_rook (dotype, nn, nval, nrhs, thresh, tsterr, nmax, a,
    afac, ainv, b, x, xact, work, rwork, iwork, nout)
    ZDRVSY_ROOK

💅 Function/Subroutine Documentation 💅

okay so here's the full signature, copied exactly because we do not mess with code:

   subroutine zdrvsy_rook (logical, dimension( * ) dotype, integer nn, integer,
       dimension( * ) nval, integer nrhs, double precision thresh, logical
       tsterr, integer nmax, complex*16, dimension( * ) a, complex*16,
       dimension( * ) afac, complex*16, dimension( * ) ainv, complex*16,
       dimension( * ) b, complex*16, dimension( * ) x, complex*16, dimension( *
       ) xact, complex*16, dimension( * ) work, double precision, dimension( *
       ) rwork, integer, dimension( * ) iwork, integer nout)
       ZDRVSY_ROOK

🎀 Purpose 🎀

ZDRVSY_ROOK tests the driver routines ZSYSV_ROOK. 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. (yes bestie, zero means show me everything 💅)
• 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 — COMPLEX*16 array, dimension (NMAX*NMAX).
• AFAC — COMPLEX*16 array, dimension (NMAX*NMAX).
• AINV — COMPLEX*16 array, dimension (NMAX*NMAX).
• B — COMPLEX*16 array, dimension (NMAX*NRHS).
• X — COMPLEX*16 array, dimension (NMAX*NRHS).
• XACT — COMPLEX*16 array, dimension (NMAX*NRHS).
• WORK — COMPLEX*16 array, dimension (NMAX*max(2,NRHS)).
• RWORK — DOUBLE PRECISION array, dimension (NMAX+2*NRHS).
• IWORK — INTEGER array, dimension (NMAX).
• NOUT — INTEGER. The unit number for output.

okay bestie, that's the page! source/version/date sign-off: LAPACK, Version 3.12.0, TESTING/LI...rvsy_rook.f(3) — and the footer didn't show a date, so I'm not inventing one. bye 💖✨
