TESTING/LIN/cchkhe.f(3)

🌸 NAME 🌸

TESTING/LIN/cchkhe.f — yep bestie, that's the manual name, and this page is all about the cchkhe test driver from the Library Functions Manual. It's giving "LAPACK quality-control queen" energy, and honestly? Obsessed 💅✨

✨ SYNOPSIS ✨

Functions/Subroutines

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

🎀 Function/Subroutine Documentation 🎀

subroutine cchkhe (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,

CCHKHE — main character routine, no cap 💖

Purpose 💖

!>
!> CCHKHE tests CHETRF, -TRI2, -TRS, -TRS2, -RFS, and -CON.

That's the whole assignment, and it ate. 💅

Parameters 💅

• DOTYPE — 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 — INTEGER. The number of values of N contained in the vector NVAL.
• NVAL — INTEGER array, dimension (NN). The values of the matrix dimension N.
• NNB — INTEGER. The number of values of NB contained in the vector NBVAL.
• NBVAL — INTEGER array, dimension (NNB). The values of the blocksize NB.
• 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 — 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 — 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 array, dimension (NMAX*NMAX).
• AFAC — COMPLEX array, dimension (NMAX*NMAX).
• AINV — COMPLEX array, dimension (NMAX*NMAX).
• B — COMPLEX array, dimension (NMAX*NSMAX) where NSMAX is the largest entry in NSVAL.
• X — COMPLEX array, dimension (NMAX*NSMAX).
• XACT — COMPLEX array, dimension (NMAX*NSMAX).
• WORK — COMPLEX array, dimension (NMAX*max(3,NSMAX)).
• RWORK — REAL array, dimension (max(NMAX,2*NSMAX)).
• IWORK — INTEGER array, dimension (NMAX).
• NOUT — INTEGER. The unit number for output.
