TESTING/LIN/schksy_aa.f(3)

💖 NAME 💖

okay so this is TESTING/LIN/schksy_aa.f, bestie — and the manual page title is TESTING/LIN/schksy_aa.f(3) from the Library Functions Manual. slay.

---

✨ SYNOPSIS ✨

Functions/Subroutines — this is the subroutine situation, no cap:

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

🧚 Function/Subroutine Documentation 🧚

here’s the full typed signature, bestie, exactly as it is:

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

🦋 Purpose 🦋

SCHKSY_AA tests SSYTRF_AA, -TRS_AA. that’s the whole purpose, and it ate. 💅

🌸 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 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. 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 REAL array, dimension (NMAX*NMAX).
• AFAC — AFAC is REAL array, dimension (NMAX*NMAX).
• AINV — AINV is REAL array, dimension (NMAX*NMAX).
• B — B is REAL array, dimension (NMAX*NSMAX) where NSMAX is the largest entry in NSVAL.
• X — X is REAL array, dimension (NMAX*NSMAX).
• XACT — XACT is REAL array, dimension (NMAX*NSMAX).
• WORK — WORK is REAL array, dimension (NMAX*max(3,NSMAX)).
• RWORK — RWORK is REAL array, dimension (max(NMAX,2*NSMAX)).
• IWORK — IWORK is INTEGER array, dimension (2*NMAX).
• NOUT — NOUT is INTEGER. the unit number for output.
