TESTING/LIN/cchkhe_rk.f(3)

🌸 NAME 🌸

cchkhe_rk is literally the star of TESTING/LIN/cchkhe_rk.f — a Library Functions Manual page, bestie. It’s a Fortran testing routine and it’s giving “I check things so you don’t have to” energy. 🎀

✨ SYNOPSIS ✨

💅 Functions/Subroutines

• subroutine cchkhe_rk — the subroutine entry in the synopsis, full signature below.
• CCHKHE_RK — yep, the all-caps name is right there too.

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

🧚 Function/Subroutine Documentation 🧚

subroutine cchkhe_rk (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( * ) e, complex, dimension( * ) ainv, complex, dimension( * )

       CCHKHE_RK

🎀 Purpose 🎀

CCHKHE_RK tests CHETRF_RK, -TRI_3, -TRS_3, and -CON_3. That’s the whole mission, and it ate. 💖

🌸 Parameters 🌸

• DOTYPE — LOGICAL array, dimension (NTYPES). These are the matrix types used for testing. Matrices of type j (for 1 <= j <= NTYPES) get tested if DOTYPE(j) = .TRUE.; if DOTYPE(j) = .FALSE., then type j is not used. Simple as that, bestie.
• 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. If you want every test ratio printed, use THRESH = 0. No hiding, periodt.
• 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).
• E — COMPLEX array, dimension (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 (2*NMAX).
• NOUT — INTEGER. The unit number for output.
