TESTING/LIN/cdrvsyx.f(3)

Okay bestie, welcome to TESTING/LIN/cdrvsyx.f(3) 💖 This page lives in the Library Functions Manual, and it’s the whole CDRVSYX situation. It’s giving LAPACK test-suite main character energy, no cap ✨

💖 NAME 💖

TESTING/LIN/cdrvsyx.f

✨ SYNOPSIS ✨

🎀 Functions/Subroutines 🎀

Here’s the synopsis, copied exactly so nobody gets lost, bestie:

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

CDRVSYX is the name on the label 👑

💅 FUNCTION/SUBROUTINE DOCUMENTATION 💅

Here’s the full signature with all the types and dimensions, character for character:

   subroutine cdrvsy (logical, dimension( * ) dotype, integer nn, integer,
       dimension( * ) nval, integer nrhs, real thresh, logical tsterr, integer
       nmax, complex, dimension( * ) a, complex, dimension( * ) afac, complex,
       dimension( * ) ainv, complex, dimension( * ) b, complex, dimension( * )
       x, complex, dimension( * ) xact, complex, dimension( * ) work, real,
       dimension( * ) rwork, integer, dimension( * ) iwork, integer nout)
       CDRVSYX

🌈 Purpose 🌈

CDRVSY tests the driver routines CSYSV, -SVX, and -SVXX. periodt 💅

Note that this file is used only when the XBLAS are available, otherwise cdrvsy.f defines this subroutine. iykyk ✨

🍓 Parameters 🍓

Okay, parameter time, bestie. Every single one, no skipping:

• DOTYPE — DOTYPE is 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 — NN is INTEGER. The number of values of N contained in the vector NVAL.
• NVAL — NVAL is INTEGER array, dimension (NN). The values of the matrix dimension N.
• NRHS — NRHS is INTEGER. The number of right hand side vectors to be generated for each linear system.
• THRESH — THRESH is REAL. 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. Flag that indicates whether error exits are to be tested.
• NMAX — NMAX is INTEGER. The maximum value permitted for N, used in dimensioning the work arrays.
• A — A is COMPLEX array, dimension (NMAX*NMAX).
• AFAC — AFAC is COMPLEX array, dimension (NMAX*NMAX).
• AINV — AINV is COMPLEX array, dimension (NMAX*NMAX).
• B — B is COMPLEX array, dimension (NMAX*NRHS).
• X — X is COMPLEX array, dimension (NMAX*NRHS).
• XACT — XACT is COMPLEX array, dimension (NMAX*NRHS).
• WORK — WORK is COMPLEX array, dimension (NMAX*max(2,NRHS)).
• RWORK — RWORK is REAL array, dimension (2*NMAX+2*NRHS).
• IWORK — IWORK is INTEGER array, dimension (NMAX).
• NOUT — NOUT is INTEGER. The unit number for output.
