💖 NAME 💖

Okay so this is the TESTING/LIN/schkps.f(3) page from the Library Functions Manual, and the manual name is TESTING/LIN/schkps.f — we're folding it in right here so it doesn't get lonely. It's the LAPACK test routine page for schkps, bestie. 💅

✨ SYNOPSIS ✨

🧚 Functions/Subroutines

       subroutine schkps (dotype, nn, nval, nnb, nbval, nrank, rankval, thresh,
           tsterr, nmax, a, afac, perm, piv, work, rwork, nout)
           SCHKPS

🎀 Function/Subroutine Documentation 🎀

   subroutine schkps (logical, dimension( * ) dotype, integer nn, integer,
       dimension( * ) nval, integer nnb, integer, dimension( * ) nbval, integer
       nrank, integer, dimension( * ) rankval, real thresh, logical tsterr,
       integer nmax, real, dimension( * ) a, real, dimension( * ) afac, real,
       dimension( * ) perm, integer, dimension( * ) piv, real, dimension( * )
       work, real, dimension( * ) rwork, integer nout)
       SCHKPS

🔥 Purpose

Literally the whole point: SCHKPS tests SPSTRF. That's the vibe. 💖

🌸 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 block size NB.
  • NRANK — NRANK is INTEGER. The number of values of RANK contained in the vector RANKVAL.
  • RANKVAL — RANKVAL is INTEGER array, dimension (NBVAL). The values of the block size NB.
  • 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).
  • PERM — PERM is REAL array, dimension (NMAX*NMAX).
  • PIV — PIV is INTEGER array, dimension (NMAX).
  • WORK — WORK is REAL array, dimension (NMAX*3).
  • RWORK — RWORK is REAL array, dimension (NMAX).
  • NOUT — NOUT is INTEGER. The unit number for output.
