Okay bestie, this is the manual page for TESTING/LIN/zchksy_rk.f(3), and it lives under the Library Functions Manual umbrella. Grab a strawberry drink and let’s get into it. 🍓✨

🌸 NAME 🌸

TESTING/LIN/zchksy_rk.f — that’s the name, periodt. 💅

✨ SYNOPSIS ✨

💅 Functions/Subroutines 💅

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

🧚 Function/Subroutine Documentation 🧚

subroutine zchksy_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, complex*16, dimension( * ) a, complex*16,

    ZCHKSY_RK

🎯 Purpose 🎯

The purpose is literally this: ZCHKSY_RK tests ZSYTRF_RK, -TRI_3, -TRS_3, and -CON_3. That’s the assignment, bestie. 💖

🌈 Parameters 🌈

  • DOTYPE — 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 — 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 — 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 — 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 — COMPLEX*16 array, dimension (NMAX*NMAX).
  • AFAC — COMPLEX*16 array, dimension (NMAX*NMAX).
  • E — COMPLEX*16 array, dimension (NMAX).
  • AINV — COMPLEX*16 array, dimension (NMAX*NMAX).
  • B — COMPLEX*16 array, dimension (NMAX*NSMAX) where NSMAX is the largest entry in NSVAL.
  • X — COMPLEX*16 array, dimension (NMAX*NSMAX).
  • XACT — COMPLEX*16 array, dimension (NMAX*NSMAX).
  • WORK — COMPLEX*16 array, dimension (NMAX*max(3,NSMAX)).
  • RWORK — DOUBLE PRECISION array, dimension (max(NMAX,2*NSMAX)).
  • IWORK — INTEGER array, dimension (2*NMAX).
  • NOUT — INTEGER. The unit number for output.
