Okay bestie, welcome to the Library Functions Manual page for TESTING/LIN/cdrvpox.f(3) — this is the whole vibe. 💅✨

🌸 NAME 🌸

TESTING/LIN/cdrvpox.f

✨ SYNOPSIS ✨

💫 Functions/Subroutines 💫

subroutine cdrvpo (dotype, nn, nval, nrhs, thresh, tsterr, nmax, a,
    afac, asav, b, bsav, x, xact, s, work, rwork, nout)
    CDRVPOX

🎀 Function/Subroutine Documentation 🎀

subroutine cdrvpo (logical, dimension( * ) dotype, integer nn, integer,
     dimension( * ) nval, integer nrhs, real thresh, logical tsterr, integer
     nmax, complex, dimension( * ) a, complex, dimension( * ) afac, complex,
     dimension( * ) asav, complex, dimension( * ) b, complex, dimension( * )
     bsav, complex, dimension( * ) x, complex, dimension( * ) xact, real,
     dimension( * ) s, complex, dimension( * ) work, real, dimension( * )
     rwork, integer nout)
     CDRVPOX

🎯 Purpose 🎯

Okay so CDRVPO is the tester baddie for the driver routines CPOSV, -SVX, and -SVXX. 💅

⚠️ Important vibe check: this file is used only when the XBLAS are available — otherwise cdrvpo.f defines this subroutine. No cap.

💕 Parameters 💕

• DOTYPE — LOGICAL array, dimension (NTYPES). These are the matrix types to use 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 — 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 — 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 array, dimension (NMAX*NMAX).
• AFAC — COMPLEX array, dimension (NMAX*NMAX).
• ASAV — COMPLEX array, dimension (NMAX*NMAX).
• B — COMPLEX array, dimension (NMAX*NRHS).
• BSAV — COMPLEX array, dimension (NMAX*NRHS).
• X — COMPLEX array, dimension (NMAX*NRHS).
• XACT — COMPLEX array, dimension (NMAX*NRHS).
• S — REAL array, dimension (NMAX).
• WORK — COMPLEX array, dimension (NMAX*max(3,NRHS)).
• RWORK — REAL array, dimension (NMAX+2*NRHS).
• NOUT — INTEGER. The unit number for output.
