TESTING/LIN/dchksy_rk.f(3)

okay so bestie, this is TESTING/LIN/dchksy_rk.f from the Library Functions Manual, and it’s literally the page for the dchksy_rk subroutine 💅✨. It’s giving “test routine with receipts,” and we’re keeping every single detail, fr fr.

🌸 NAME 🌸

TESTING/LIN/dchksy_rk.f — the manual page for dchksy_rk. That’s the name, bestie 🫶.

✨ SYNOPSIS ✨

🧚 Functions/Subroutines 🧚

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

DCHKSY_RK is the routine label, and yes it’s iconic 👑.

🎀 Purpose 🎀

DCHKSY_RK tests DSYTRF_RK, -TRI_3, -TRS_3, and -CON_3. That’s the whole vibe: it’s running the checks and collecting the receipts 💖.

💅 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.

okay that’s the whole page, bestie 💖 cute little sign-off: this is LAPACK Version 3.12.0, source TESTING/LIN/dchksy_rk.f(3), and the footer doesn’t print a date, so I’m not inventing one — periodt 💅🫶
