💖 NAME 💖

okay bestie, this is the Library Functions Manual page for TESTING/LIN/zchksy_rook.f — a.k.a. the ZCHKSY_ROOK test-driver page. 💅

📚 Function/Subroutine Documentation 📚

subroutine zchksy_rook (logical, dimension( * ) dotype, integer nn, integer,
    dimension( * ) nval, integer nnb, integer, dimension( * ) nbval, integer

    ZCHKSY_ROOK

🎯 Purpose 🎯

ZCHKSY_ROOK tests ZSYTRF_ROOK, -TRI_ROOK, -TRS_ROOK, and -CON_ROOK. that's the whole assignment, and it ate. 🔥

🧸 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).
  • 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. 🖨️
