💖 NAME 💖

okay so this is the TESTING/LIN/schkpo.f(3) page, and it’s all about the schkpo routine bestie. Unix manual energy, but make it group chat 💅

✨ SYNOPSIS ✨

🎀 Functions/Subroutines

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

🌸 Function/Subroutine Documentation 🌸

subroutine schkpo (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)
    SCHKPO

🧚 Purpose

SCHKPO tests SPOTRF, -TRI, -TRS, -RFS, and -CON. 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 (NMAX).
  • NOUT — NOUT is INTEGER. The unit number for output.

okay bestie, sign-off time 🫶 this footer is giving LAPACK, Version 3.12.0, and the TESTING/LIN/schkpo.f(3) tag — periodt 💖✨
