ZDRVAC(3)

okay so this is zdrvac.f(3) from the Library Functions Manual, and we’re about to read it together like it’s the most iconic group-chat lore ever. 💅✨

✨ NAME ✨

The NAME section is literally just this absolute path, no cap:

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

✨ SYNOPSIS ✨

Functions/Subroutines

There is one subroutine here, and its name is ZDRVAC. The synopsis tea is:

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

💖 Function/Subroutine Documentation 💖

okay bestie, here is the full signature in all its dimensional glory — do not panic, it’s just a lot of dimension( * ) doing its thing. 🫶

   subroutine ZDRVAC (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
       nout)
       ZDRVAC

Purpose:

ZDRVAC tests ZCPOSV. That’s the whole purpose, periodt. ✨

Parameters

okay so every single parameter, no skipping, fr fr. 🧚

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

okay that’s the whole page. Footer vibes: source/version is LAPACK Version 3.12.0, the file is /home/abui...IN/zdrvac.f(3), and there’s no date printed, so I’m not inventing one — periodt. 💖✨🎀
