TESTING/LIN/zdrvgex.f(3)

💖 NAME 💖

Bestie, this page is for TESTING/LIN/zdrvgex.f, and yes, it lives in the Library Functions Manual — iconic little corner of LAPACK, no cap ✨

🦋 SYNOPSIS 🦋

🎀 Functions/Subroutines 🎀

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

💅 Function/Subroutine Documentation 💅

subroutine zdrvge (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( * ) asav, complex*16,
    dimension( * ) b, complex*16, dimension( * ) bsav, complex*16,
    dimension( * ) x, complex*16, dimension( * ) xact, double precision,
    dimension( * ) s, complex*16, dimension( * ) work, double precision,
    dimension( * ) rwork, integer, dimension( * ) iwork, integer nout)
    ZDRVGEX

🌸 Purpose 🌸

Okay so, ZDRVGE tests the driver routines ZGESV, -SVX, and -SVXX. 💖

And heads up, bestie: this file is used only when the XBLAS are available. Otherwise zdrvge.f defines this subroutine. The vibe check is very specific here 👀

🎀 Parameters 🎀

• DOTYPE — DOTYPE is LOGICAL array, dimension (NTYPES). It's the matrix types to be used for testing, fr fr. 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. It's the number of values of N contained in the vector NVAL.
• NVAL — NVAL is INTEGER array, dimension (NN). These are the values of the matrix column dimension N.
• NRHS — NRHS is INTEGER. It's the number of right hand side vectors to be generated for each linear system.
• THRESH — THRESH is DOUBLE PRECISION. It's 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. This flag indicates whether error exits are to be tested.
• NMAX — NMAX is INTEGER. It's the maximum value permitted for N, used in dimensioning the work arrays.
• A — A is COMPLEX*16 array, dimension (NMAX*NMAX).
• AFAC — AFAC is COMPLEX*16 array, dimension (NMAX*NMAX).
• ASAV — ASAV is COMPLEX*16 array, dimension (NMAX*NMAX).
• B — B is COMPLEX*16 array, dimension (NMAX*NRHS).
• BSAV — BSAV is COMPLEX*16 array, dimension (NMAX*NRHS).
• X — X is COMPLEX*16 array, dimension (NMAX*NRHS).
• XACT — XACT is COMPLEX*16 array, dimension (NMAX*NRHS).
• S — S is DOUBLE PRECISION array, dimension (2*NMAX).
• WORK — WORK is COMPLEX*16 array, dimension (NMAX*max(3,NRHS)).
• RWORK — RWORK is DOUBLE PRECISION array, dimension (2*NRHS+NMAX).
• IWORK — IWORK is INTEGER array, dimension (NMAX).
• NOUT — NOUT is INTEGER. It's the unit number for output.

Okay bye bestie! 💋 This cutie came from LAPACK Version 3.12.0, page TESTING/LIN/zdrvgex.f(3) — that's the footer, and we are obsessed with the whole thing 🫶✨
