ZDRVAB(3)

🌸 NAME 🌸

okay bestie, this is ZDRVAB(3) from the Library Functions Manual 💅 and the NAME line is literally this path, no cap:

/home/abuild/rpmbuild/BUILD/lapack-static-3.12.0-build/lapack-3.12.0/TESTING/LIN/zdrvab.f

✨ SYNOPSIS ✨

Functions/Subroutines

       subroutine ZDRVAB (dotype, nm, mval, nns, nsval, thresh, nmax, a, afac,
           b, x, work, rwork, swork, iwork, nout)
           ZDRVAB

💜 Function/Subroutine Documentation 💜

here’s the full signature again, but with all the type crumbs this time 🫶:

   subroutine ZDRVAB (logical, dimension( * ) dotype, integer nm, integer,
       dimension( * ) mval, integer nns, integer, dimension( * ) nsval, double
       precision thresh, integer nmax, complex*16, dimension( * ) a,
       complex*16, dimension( * ) afac, complex*16, dimension( * ) b,
       complex*16, dimension( * ) x, complex*16, dimension( * ) work, double
       precision, dimension( * ) rwork, complex, dimension( * ) swork, integer,
       dimension( * ) iwork, integer nout)
       ZDRVAB

🎀 Purpose 🎀

the source is very extra and wraps this in Doxygen !> comments, so here’s the exact vibe:

🦋 Parameters 🦋

every parameter gets its own moment, and I’m keeping every dimension/value exactly as written:

• 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.
• NM — INTEGER. The number of values of M contained in the vector MVAL.
• MVAL — INTEGER array, dimension (NM). The values of the matrix row dimension M.
• NNS — INTEGER. The number of values of NRHS contained in the vector NSVAL.
• NSVAL — INTEGER array, dimension (NNS). The values of the number of right hand sides NRHS.
• 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.
• NMAX — INTEGER. The maximum value permitted for M or N, used in dimensioning the work arrays.
• A — COMPLEX*16 array, dimension (NMAX*NMAX).
• AFAC — COMPLEX*16 array, dimension (NMAX*NMAX).
• B — COMPLEX*16 array, dimension (NMAX*NSMAX) where NSMAX is the largest entry in NSVAL.
• X — COMPLEX*16 array, dimension (NMAX*NSMAX).
• WORK — COMPLEX*16 array, dimension (NMAX*max(3,NSMAX*2)).
• RWORK — DOUBLE PRECISION array, dimension NMAX.
• SWORK — COMPLEX array, dimension (NMAX*(NSMAX+NMAX)).
• IWORK — INTEGER array, dimension NMAX.
• NOUT — INTEGER. The unit number for output.
