/home/abui...chksy_rk.f(3)

okay so bestie, this is the Library Functions Manual page for /home/abui...chksy_rk.f(3). Yes, that’s the manual-page name; the full source path lives under NAME and it’s giving “very specific build directory” energy. 🎀

💖 NAME

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

That path is literally it — no extra prose in the NAME section. 💅

✨ SYNOPSIS ✨

🧚 Functions/Subroutines

• subroutine DCHKSY_RK (...) — the subroutine this page documents. Here’s the exact synopsis block:

       subroutine DCHKSY_RK (dotype, nn, nval, nnb, nbval, nns, nsval, thresh,
           tsterr, nmax, a, afac, e, ainv, b, x, xact, work, rwork, iwork,
           nout)
           DCHKSY_RK

🫶 Function/Subroutine Documentation

Full documented signature, exactly as given:

   subroutine DCHKSY_RK (logical, dimension( * ) dotype, integer nn, integer,
       dimension( * ) nval, integer nnb, integer, dimension( * ) nbval, integer
       nns, integer, dimension( * ) nsval, double precision thresh, logical
       tsterr, integer nmax, double precision, dimension( * ) a, double
       precision, dimension( * ) afac, double precision, dimension( * ) e,
       double precision, dimension( * ) ainv, double precision, dimension( * )
       b, double precision, dimension( * ) x, double precision, dimension( * )
       xact, double precision, dimension( * ) work, double precision,
       dimension( * ) rwork, integer, dimension( * ) iwork, integer nout)
       DCHKSY_RK

🎯 Purpose

DCHKSY_RK tests DSYTRF_RK, -TRI_3, -TRS_3, and -CON_3.

🧪 Parameters

• DOTYPE — DOTYPE is 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.
• NN — NN is INTEGER. The number of values of N contained in the vector NVAL.
• NVAL — NVAL is INTEGER array, dimension (NN). The values of the matrix dimension N.
• NNB — NNB is INTEGER. The number of values of NB contained in the vector NBVAL.
• NBVAL — NBVAL is INTEGER array, dimension (NNB). The values of the blocksize NB.
• 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.
• TSTERR — TSTERR is LOGICAL. 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 DOUBLE PRECISION array, dimension (NMAX*NMAX).
• AFAC — AFAC is DOUBLE PRECISION array, dimension (NMAX*NMAX).
• E — E is DOUBLE PRECISION array, dimension (NMAX).
• AINV — AINV is DOUBLE PRECISION array, dimension (NMAX*NMAX).
• B — B is DOUBLE PRECISION array, dimension (NMAX*NSMAX), where NSMAX is the largest entry in NSVAL.
• X — X is DOUBLE PRECISION array, dimension (NMAX*NSMAX), where NSMAX is the largest entry in NSVAL.
• XACT — XACT is DOUBLE PRECISION array, dimension (NMAX*NSMAX), where NSMAX is the largest entry in NSVAL.
• WORK — WORK is DOUBLE PRECISION array, dimension (NMAX*max(3,NSMAX)).
• RWORK — RWORK is DOUBLE PRECISION array, dimension (max(NMAX,2*NSMAX)).
• IWORK — IWORK is INTEGER array, dimension (2*NMAX).
• NOUT — NOUT is INTEGER. The unit number for output.

that’s the whole page, bestie 🫶✨ The sign-off from the bottom is LAPACK Version 3.12.0 and the page is /home/abui...chksy_rk.f(3) — and since no date is printed in that footer, I’m not making one up. 💜
