🎀 CCHKHE_ROOK — Library Functions Manual 🎀

File bestie: TESTING/LIN/cchkhe_rook.f. Manual cutie: Library Functions Manual. Okay now let's get into the group chat, because this page is lowkey all about testing the ROOK routines and not missing a single detail. 💅✨

✨ NAME ✨

TESTING/LIN/cchkhe_rook.f — that's the file, bestie. No extra name-line lore, periodt. 🫶

🧚 SYNOPSIS 🧚

🦋 Functions/Subroutines 🦋

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

CCHKHE_ROOK is the icon we're documenting, no cap. 👑

🫶 Purpose 🫶

The purpose section is literally serving this exact energy:

!>
!> CCHKHE_ROOK tests CHETRF_ROOK, -TRI_ROOK, -TRS_ROOK,
!> and -CON_ROOK.
!>

So yes: CCHKHE_ROOK tests CHETRF_ROOK, -TRI_ROOK, -TRS_ROOK, and -CON_ROOK. That's the whole assignment, and she ate. 🔥

🌈 Parameters 🌈

• DOTYPE — LOGICAL array, dimension (NTYPES). This is the matrix-type guest list 💅. 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) — yes, that parenthesis is exactly how it shows up in the source, bestie, don't come for me 😭.
• IWORK — INTEGER array, dimension (2*NMAX).
• NOUT — INTEGER. The unit number for output.
