🌸 NAME 🌸

okay so bestie, this is the LAPACK manual page for TESTING/LIN/cdrvsy.f(3) from the Library Functions Manual — and the main character is cdrvsy, a test-driver subroutine living its best life in TESTING/LIN/cdrvsy.f. 💅

✨ SYNOPSIS ✨

Functions/Subroutines

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

💖 Function/Subroutine Documentation 💖

🧚 subroutine cdrvsy

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)
     CDRVSY

Purpose

CDRVSY tests the driver routines CSYSV and -SVX. ✨

🎀 Parameters 🎀

• DOTYPE — DOTYPE is LOGICAL array, dimension (NTYPES). It tells you which matrix types get 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. 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 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 REAL. 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 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 (NMAX+2*NRHS).
• IWORK — IWORK is INTEGER array, dimension (NMAX).
• NOUT — NOUT is INTEGER. It’s the unit number for output.
