CCHKSY_ROOK.F(3)

💖 NAME 💖

Okay so, bestie: this page is from the Library Functions Manual, and it’s all about <purple>TESTING/LIN/cchksy_rook.f</purple>. That’s the name. No cap. 🫶

✨ SYNOPSIS ✨

🧚 Functions/Subroutines 🧚

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

🦋 Function/Subroutine Documentation 🦋

   subroutine cchksy_rook (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, dimension( * ) iwork, integer nout)
       CCHKSY_ROOK

🎯 Purpose 🎯

The tea is: CCHKSY_ROOK tests CSYTRF_ROOK, -TRI_ROOK, -TRS_ROOK, and -CON_ROOK. That’s the whole purpose, and the source comment keeps it super literal:

🧸 Parameters 🧸

• DOTYPE — DOTYPE is LOGICAL array, dimension (NTYPES). It’s the matrix-type menu for testing: matrices of type j (for 1 <= j <= NTYPES) get used if DOTYPE(j) = .TRUE.; if DOTYPE(j) = .FALSE., then type j is not used. 💅
• NN — NN is INTEGER. It’s the number of values of N contained in the vector NVAL.
• NVAL — NVAL is INTEGER array, dimension (NN). These are the values of the matrix dimension N.
• NNB — NNB is INTEGER. It’s the number of values of NB contained in the vector NBVAL.
• NBVAL — NBVAL is INTEGER array, dimension (NNB). These are the values of the blocksize NB.
• NNS — NNS is INTEGER. It’s the number of values of NRHS contained in the vector NSVAL.
• NSVAL — NSVAL is INTEGER array, dimension (NNS). These are the values of the number of right hand sides NRHS.
• THRESH — THRESH is REAL. It’s the threshold value for the test ratios. A result is included in the output file if RESULT >= THRESH. Want 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 array, dimension (NMAX*NMAX).
• AFAC — AFAC is COMPLEX array, dimension (NMAX*NMAX).
• AINV — AINV is COMPLEX array, dimension (NMAX*NMAX).
• B — B is COMPLEX array, dimension (NMAX*NSMAX), where NSMAX is the largest entry in NSVAL.
• X — X is COMPLEX array, dimension (NMAX*NSMAX).
• XACT — XACT is COMPLEX array, dimension (NMAX*NSMAX).
• WORK — WORK is COMPLEX array, dimension (NMAX*max(3,NSMAX)).
• RWORK — RWORK is REAL array, dimension (max(NMAX,2*NSMAX)).
• IWORK — IWORK is INTEGER array, dimension (2*NMAX).
• NOUT — NOUT is INTEGER. The unit number for output.
