okay so this page is from the Library Functions Manual, and the page itself is /home/abui...vsy_rook.f(3) — yes, the title is a whole path, she’s extra like that 💅.

🌸 NAME 🌸

The name is literally this full path, no cap:

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

✨ SYNOPSIS ✨

🧚 Functions/Subroutines 🧚

Bestie, the synopsis serves you this signature:

subroutine CDRVSY_ROOK (dotype, nn, nval, nrhs, thresh, tsterr, nmax, a,
    afac, ainv, b, x, xact, work, rwork, iwork, nout)
    CDRVSY_ROOK

🦋 Function/Subroutine Documentation 🦋

Here’s the full documented signature with all the types and dimensions:

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

🎯 Purpose

CDRVSY_ROOK tests the driver routines CSYSV_ROOK. That’s the whole purpose, and honestly, iconic.

🧾 Parameters

• DOTYPE — this is the LOGICAL array, dimension (NTYPES) that says which matrix types get used for testing. Matrix type j (for 1 <= j <= NTYPES) is used if DOTYPE(j) = .TRUE.; if DOTYPE(j) = .FALSE., then type j is not used. Periodt.
• NN — NN is INTEGER, and it’s the number of values of N contained in the vector NVAL.
• NVAL — NVAL is INTEGER array, dimension (NN), holding the values of the matrix dimension N.
• NRHS — NRHS is INTEGER, the number of right hand side vectors to be generated for each linear system.
• THRESH — THRESH is 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 — TSTERR is LOGICAL, a flag that indicates whether error exits are to be tested.
• NMAX — NMAX is INTEGER, the maximum value permitted for N, used in dimensioning the work arrays.
• A — A is COMPLEX array, dimension (NMAX*NMAX). That’s the whole description, bestie.
• AFAC — AFAC is COMPLEX array, dimension (NMAX*NMAX).
• AINV — AINV is COMPLEX array, dimension (NMAX*NMAX).
• B — B is COMPLEX array, dimension (NMAX*NRHS).
• X — X is COMPLEX array, dimension (NMAX*NRHS).
• XACT — XACT is COMPLEX array, dimension (NMAX*NRHS).
• WORK — the original parameter block here is just an empty !>; no extra description is given in this entry. The synopsis signature above lists it as complex, dimension( * ).
• RWORK — RWORK is REAL array, dimension (NMAX+2*NRHS).
• IWORK — IWORK is INTEGER array, dimension (NMAX).
• NOUT — NOUT is INTEGER, the unit number for output.
