TESTING/LIN/zchkpp.f(3)

🎀 NAME 🎀

TESTING/LIN/zchkpp.f — from the Library Functions Manual, bestie. This page is all about the zchkpp subroutine, and she is iconic. 💅✨

✨ SYNOPSIS ✨

🦋 Functions/Subroutines 🦋

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

💖 Function/Subroutine Documentation 💖

subroutine zchkpp (logical, dimension( * ) dotype, integer nn, integer,
       dimension( * ) nval, integer nns, integer, dimension( * ) nsval, double
       precision thresh, logical tsterr, integer nmax, complex*16, dimension( *
       ) a, complex*16, dimension( * ) afac, complex*16, dimension( * ) ainv,
       complex*16, dimension( * ) b, complex*16, dimension( * ) x, complex*16,
       dimension( * ) xact, complex*16, dimension( * ) work, double precision,
       dimension( * ) rwork, integer nout)
       ZCHKPP

🎯 Purpose

Okay so ZCHKPP tests ZPPTRF, -TRI, -TRS, -RFS, and -CON — that’s the whole purpose, no cap. ✨

💅 Parameters 💅

• DOTYPE — LOGICAL array, dimension (NTYPES). These are the matrix types for testing, bestie: 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.
• 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. This is the threshold value for the test ratios. A result gets included in the output file if RESULT >= THRESH. Want 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+1)/2).
• AFAC — COMPLEX*16 array, dimension (NMAX*(NMAX+1)/2).
• AINV — COMPLEX*16 array, dimension (NMAX*(NMAX+1)/2).
• 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)).
• NOUT — INTEGER. The unit number for output.
