TESTING/LIN/cchkpp.f(3)

🎀 NAME 🎀

TESTING/LIN/cchkpp.f is the page, bestie — and yes, it’s repping the Library Functions Manual. This is the CCHKPP test-checker subroutine, and we’re gonna go through every single parameter like it’s the group-chat receipts. 💅✨

🌸 SYNOPSIS 🌸

🦋 Functions/Subroutines 🦋

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

💖 Function/Subroutine Documentation 💖

Okay so here’s the full signature, typed out exactly, no cap:

   subroutine cchkpp (logical, dimension( * ) dotype, integer nn, integer,
       dimension( * ) nval, integer nns, integer, dimension( * ) nsval, real
       thresh, logical tsterr, integer nmax, complex, dimension( * ) a,
       complex, dimension( * ) afac, complex, dimension( * ) ainv, complex,
       dimension( * ) b, complex, dimension( * ) x, complex, dimension( * )
       xact, complex, dimension( * ) work, real, dimension( * ) rwork, integer
       nout)

And the label for this whole moment is CCHKPP. 👑

✨ Purpose ✨

CCHKPP tests CPPTRF, -TRI, -TRS, -RFS, and -CON. That’s the whole purpose, periodt. 💖

🎀 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. iykyk 💫
• 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.
• 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 COMPLEX array, dimension (NMAX*(NMAX+1)/2).
• AFAC — AFAC is COMPLEX array, dimension (NMAX*(NMAX+1)/2).
• AINV — AINV is COMPLEX array, dimension (NMAX*(NMAX+1)/2).
• B — B is COMPLEX array, dimension (NMAX*NSMAX) where NSMAX is the largest entry in NSVAL.
• X — X is COMPLEX array, dimension (NMAX*NSMAX).
• XACT — XACT is COMPLEX array, dimension (NMAX*NSMAX).
• WORK — WORK is COMPLEX array, dimension (NMAX*max(3,NSMAX)).
• RWORK — RWORK is REAL array, dimension (max(NMAX,2*NSMAX)).
• NOUT — NOUT is INTEGER. The unit number for output.
