CCHKTR(3)

🌸 NAME 🌸

okay so this page is from the Library Functions Manual, and the NAME is literally this full path, no cap:

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

✨ SYNOPSIS ✨

🛠️ Functions/Subroutines

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

💖 FUNCTION/SUBROUTINE DOCUMENTATION 💖

here's the full signature tea 🫖 — every type and dimension stays exactly as written:

   subroutine CCHKTR (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( * ) ainv, complex,
       dimension( * ) b, complex, dimension( * ) x, complex, dimension( * )
       xact, complex, dimension( * ) work, real, dimension( * ) rwork, integer
       nout)
       CCHKTR

🎯 Purpose

CCHKTR tests CTRTRI, -TRS, -RFS, and -CON, and CLATRS(3). that's the whole mood 💅

🧾 Parameters

• DOTYPE — LOGICAL array, dimension (NTYPES). this is the matrix-types test menu, bestie: 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 column 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 leading dimension of the work arrays. NMAX >= the maximum value of N in NVAL.
• A — 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)).
• NOUT — INTEGER. the unit number for output. 💜

and that's the sign-off, bestie: the footer says LAPACK Version 3.12.0 and points at /home/abui...IN/cchktr.f(3). no separate date is listed in this footer, so i'm not inventing one 😭💅
