💖 NAME 💖

okay so this is the Library Functions Manual page for /home/abui...drvsy_rk.f(3), and the actual source file it’s documenting is:

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

✨ SYNOPSIS ✨

🦋 Functions/Subroutines

Here’s the group-chat summons, verbatim:

   Functions/Subroutines
       subroutine CDRVSY_RK (dotype, nn, nval, nrhs, thresh, tsterr, nmax, a,
           afac, e, ainv, b, x, xact, work, rwork, iwork, nout)
           CDRVSY_RK

🫶 Function/Subroutine Documentation 🫶

The full signature is literally this:

   subroutine CDRVSY_RK (logical, dimension( * ) dotype, integer nn, integer,
       dimension( * ) nval, integer nrhs, real thresh, logical tsterr, integer
       nmax, complex, dimension( * ) a, complex, dimension( * ) afac, complex,
       dimension( * ) e, complex, dimension( * ) ainv, complex, dimension( * )
       b, complex, dimension( * ) x, complex, dimension( * ) xact, complex,
       dimension( * ) work, real, dimension( * ) rwork, integer, dimension( * )
       iwork, integer nout)
       CDRVSY_RK

🌸 Purpose

The purpose block is short and iconic:

!>
!> CDRVSY_RK tests the driver routines CSYSV_RK.

So yeah — it’s the test driver for CSYSV_RK, no cap. 💅

🍓 Parameters

• DOTYPE — LOGICAL array, dimension (NTYPES). These are the matrix types to be used for testing. Matrices of type j are used for testing if 1 <= j <= NTYPES and 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).
• E — COMPLEX array, dimension (NMAX).
• AINV — COMPLEX array, dimension (NMAX*NMAX).
• B — COMPLEX array, dimension (NMAX*NRHS).
• X — COMPLEX array, dimension (NMAX*NRHS).
• XACT — COMPLEX array, dimension (NMAX*NRHS).
• WORK — bestie, the original only has a bare !> here. No description text. 🙈
• RWORK — REAL array, dimension (NMAX+2*NRHS).
• IWORK — INTEGER array, dimension (NMAX).
• NOUT — INTEGER. The unit number for output.

okay that’s the whole page, bestie 💅 — LAPACK, Version 3.12.0, and the footer path is /home/abui...drvsy_rk.f(3). Bye, go test those driver routines 🫶✨
