🌸 TESTING/LIN/schksy.f(3) 🌸

okay bestie, this is the LAPACK Library Functions Manual page for TESTING/LIN/schksy.f — and yes, it's giving “testing routine main character energy.” 💅✨

✨ NAME ✨

TESTING/LIN/schksy.f — that's the name, periodt. This is the file we're talking about. 🎀

🦋 SYNOPSIS 🦋

💖 Functions/Subroutines 💖

  • subroutine schksy (dotype, nn, nval, nnb, nbval, nns, nsval, thresh, tsterr, nmax, a, afac, ainv, b, x, xact, work, rwork, iwork, nout) — SCHKSY, the subroutine herself. 👑

🌟 subroutine schksy 🌟

subroutine schksy (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,

    ) rwork, integer, dimension( * ) iwork, integer nout)
    SCHKSY

🎯 Purpose 🎯

The whole point, bestie: SCHKSY tests SSYTRF, -TRI2, -TRS, -TRS2, -RFS, and -CON. That's the mission. That's the vibe. 💖🔥

🧾 Parameters 🧾

  • DOTYPE — it's a LOGICAL array, dimension (NTYPES). These are 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. So basically, it's the yes/no list for which matrix types get invited to the test party. 🎀
  • NN — INTEGER. The number of values of N contained in the vector NVAL.
  • 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 — 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. No cap: if you want all the tea, set it to zero. 🍓
  • 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 — REAL array, dimension (NMAX*NMAX).
  • AFAC — REAL array, dimension (NMAX*NMAX).
  • AINV — REAL array, dimension (NMAX*NMAX).
  • B — REAL array, dimension (NMAX*NSMAX) where NSMAX is the largest entry in NSVAL.
  • X — REAL array, dimension (NMAX*NSMAX).
  • XACT — REAL array, dimension (NMAX*NSMAX).
  • WORK — REAL array, dimension (NMAX*max(3,NSMAX)).
  • RWORK — REAL array, dimension (max(NMAX,2*NSMAX)).
  • IWORK — INTEGER array, dimension (2*NMAX).
  • NOUT — INTEGER. The unit number for output.
bestie, every dimension and every type up there is load-bearing. Do not play with them. 🙈💀
