TESTING/LIN/zdrvsyx.f(3)

🎀 NAME 🎀

okay so bestie, this is the manual page for TESTING/LIN/zdrvsyx.f — Library Functions Manual, section 3, and yes it’s giving very specific LAPACK testing energy.

✨ SYNOPSIS ✨

Functions/Subroutines

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

🛠️ Function/Subroutine Documentation 🛠️

subroutine zdrvsy (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)
       ZDRVSYX

🎯 Purpose

ZDRVSY tests the driver routines ZSYSV, -SVX, and -SVXX.

Note: this file is used only when the XBLAS are available, otherwise zdrvsy.f defines this subroutine.

🧪 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 — 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 (2*NMAX+2*NRHS).
• IWORK — INTEGER array, dimension (NMAX).
• NOUT — INTEGER. The unit number for output.
