SCHKPP(3)

💅 SCHKPP(3) — Library Functions Manual 💅

Okay bestie, welcome to the <pink>SCHKPP(3)</pink> page. The header vibe is Library Functions Manual, and the page file path is /home/abui...IN/schkpp.f(3). We’re so back. 🫶

💖 NAME 💖

The NAME here is literally the whole path, no cap:

/home/abuild/rpmbuild/BUILD/lapack-static-3.12.0-build/lapack-3.12.0/TESTING/LIN/schkpp.f

That’s the whole name, bestie. Iconic behavior. ✨

✨ SYNOPSIS ✨

Functions/Subroutines

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

The subroutine name is SCHKPP. Slay. 💅

🦋 Function/Subroutine Documentation 🦋

Here’s the typed signature, exactly as it appears:

subroutine SCHKPP (logical, dimension( * ) dotype, integer nn, integer,
    dimension( * ) nval, 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, real, dimension( * ) xact, real, dimension( * )
    work, real, dimension( * ) rwork, integer, dimension( * ) iwork, integer
    nout)
SCHKPP

🎀 Purpose 🎀

SCHKPP tests SPPTRF, -TRI, -TRS, -RFS, and -CON. That’s the whole purpose, and it ate. 🔥

🌸 Parameters 🌸

• DOTYPE — DOTYPE is LOGICAL array, dimension (NTYPES). It’s the “which matrix types are we testing” squad. 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. Periodt.
• NN — NN is INTEGER. It’s the number of values of N contained in the vector NVAL.
• NVAL — NVAL is INTEGER array, dimension (NN). These are the values of the matrix dimension N.
• NNS — NNS is INTEGER. It’s the number of values of NRHS contained in the vector NSVAL.
• NSVAL — NSVAL is INTEGER array, dimension (NNS). These are the values of the number of right hand sides NRHS.
• THRESH — THRESH is REAL. It’s 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+1)/2).
• AFAC — AFAC is REAL array, dimension (NMAX*(NMAX+1)/2).
• AINV — AINV is REAL array, dimension (NMAX*(NMAX+1)/2).
• 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.
