DCHKSY(3)

hey bestie 💖 welcome to the dchksy.f(3) page from the Library Functions Manual — LAPACK testing energy, let's go.

🌸 NAME 🌸

this page is literally about this file path, no cap:

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

✨ SYNOPSIS ✨

🧚 Functions/Subroutines 🧚

okay so the synopsis is giving:

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

💫 Function/Subroutine Documentation 💫

here's the full typed signature, bestie:

subroutine DCHKSY (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( * ) 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

🎀 Purpose 🎀

the whole point, literally:

!>
!> DCHKSY tests DSYTRF, -TRI2, -TRS, -TRS2, -RFS, and -CON.

💅 Parameters 💅

• DOTYPE — LOGICAL array, dimension (NTYPES). this is the matrix-types menu. matrices of type j (where 1 <= j <= NTYPES) get used for testing if DOTYPE(j) = .TRUE.; if DOTYPE(j) = .FALSE., then type j is literally not used, periodt.
• NN — INTEGER. the number of values of N contained in the vector NVAL, bestie.
• NVAL — INTEGER array, dimension (NN). the values of the matrix dimension N.
• NNB — INTEGER. the number of values of NB contained in the vector NBVAL.
• NBVAL — INTEGER array, dimension (NNB). the values of the blocksize NB.
• 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 gets included in the output file if RESULT >= THRESH. if you want 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 — DOUBLE PRECISION array, dimension (NMAX*NMAX). it's the A array, no cap.
• AFAC — DOUBLE PRECISION array, dimension (NMAX*NMAX). the AFAC array, slay.
• AINV — DOUBLE PRECISION array, dimension (NMAX*NMAX). the AINV array, iconic.
• B — DOUBLE PRECISION array, dimension (NMAX*NSMAX) where NSMAX is the largest entry in NSVAL. the B array, bestie.
• X — DOUBLE PRECISION array, dimension (NMAX*NSMAX). the X array, periodt.
• XACT — DOUBLE PRECISION array, dimension (NMAX*NSMAX). the XACT array, for real.
• WORK — DOUBLE PRECISION array, dimension (NMAX*max(3,NSMAX)). the WORK array, doing its thing.
• RWORK — DOUBLE PRECISION array, dimension (max(NMAX,2*NSMAX)). the RWORK array, living its truth.
• IWORK — INTEGER array, dimension (2*NMAX). the IWORK array, integer energy.
• NOUT — INTEGER. the unit number for output.
