CCHKPO(3)

💅 NAME

okay so bestie, welcome to the Library Functions Manual page for cchkpo.f(3) 💅 the manual name is folded right in here, and the actual NAME path is:

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

also the page header/footer path is /home/abui...IN/cchkpo.f(3) if you’re keeping score 🫶

✨ SYNOPSIS

🌈 Functions/Subroutines

CCHKPO is the subroutine, and the synopsis is right here:

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

🎀 Function/Subroutine Documentation

here’s the full signature with all the types, dimensions, and * vibes:

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

CCHKPO (again, iconic 💫)

💖 Purpose

the source comment literally says: CCHKPO tests CPOTRF, -TRI, -TRS, -RFS, and -CON ✨

🦋 Parameters

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