CDRVPB(3)

💖 NAME 💖

/home/abuild/rpmbuild/BUILD/lapack-static-3.12.0-build/lapack-3.12.0/TESTING/LIN/cdrvpb.f — that's the whole name, bestie. This is the LAPACK manual page for CDRVPB(3) from the Library Functions Manual, section 3, and it's lowkey the test-driver subroutine that checks CPBSV and -SVX.

✨ SYNOPSIS ✨

🌸 Functions/Subroutines

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

🎀 Function/Subroutine Documentation 🎀

subroutine CDRVPB (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)
       CDRVPB

🎯 Purpose

CDRVPB tests the driver routines CPBSV and -SVX. That's the whole flex. It runs the tests, bestie. 💅

🔍 Parameters

• DOTYPE — LOGICAL array, dimension (NTYPES). These are the matrix types to use for testing. Matrices of type j (for 1 <= j <= NTYPES) get used for testing if DOTYPE(j) = .TRUE.; if DOTYPE(j) = .FALSE., then type j is not used. No cap.
• 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. This is the N menu, periodt.
• NRHS — INTEGER. The number of right hand side vectors to be generated for each linear system. RHS girlies rise. 🫶
• THRESH — REAL. The threshold value for the test ratios. A result is included in the output file if RESULT >= THRESH. Wanna see every test ratio printed? Use THRESH = 0. Obsessed with transparency.
• TSTERR — LOGICAL. Flag that indicates whether error exits are to be tested. So, yes/no on the error-exit vibe check.
• NMAX — INTEGER. The maximum value permitted for N, used in dimensioning the work arrays. Big N energy.
• 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. Where the receipts go. 🧾

💖 okay that's the whole page, bestie. Cute little footer sign-off: this is LAPACK Version 3.12.0, page path /home/abui...IN/cdrvpb.f(3). The page doesn't print a separate date, so I'm not inventing one — periodt. 💅
