TESTING/LIN/zchkpo.f(3)

💅 zchkpo.f — from the Library Functions Manual 🌸

Okay bestie, this is TESTING/LIN/zchkpo.f(3), and it's giving very specific LAPACK testing routine energy. Pull up a chair, we're getting into it. 🫶

🌸 NAME 🌸

TESTING/LIN/zchkpo.f

✨ SYNOPSIS ✨

Functions/Subroutines

Here's the synopsis, character for character, no cap:

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

Full signature time, bestie — this is the whole cast list:

subroutine zchkpo (logical, dimension( * ) dotype, integer nn, integer,
     dimension( * ) nval, integer nnb, integer, dimension( * ) nbval, 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)

ZCHKPO

Purpose

ZCHKPO tests ZPOTRF, -TRI, -TRS, -RFS, and -CON. That's the whole vibe of this routine. 🔥

Parameters

• DOTYPE — DOTYPE is LOGICAL array, dimension (NTYPES). These are 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 DOUBLE PRECISION. 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*16 array, dimension (NMAX*NMAX).
• AFAC — AFAC is COMPLEX*16 array, dimension (NMAX*NMAX).
• AINV — AINV is COMPLEX*16 array, dimension (NMAX*NMAX).
• B — B is COMPLEX*16 array, dimension (NMAX*NSMAX) where NSMAX is the largest entry in NSVAL.
• X — X is COMPLEX*16 array, dimension (NMAX*NSMAX).
• XACT — XACT is COMPLEX*16 array, dimension (NMAX*NSMAX).
• WORK — WORK is COMPLEX*16 array, dimension (NMAX*max(3,NSMAX)).
• RWORK — RWORK is DOUBLE PRECISION array, dimension (NMAX+2*NSMAX).
• NOUT — NOUT is INTEGER. The unit number for output.
