ZCHKTR(3)

💖 ZCHKTR(3) 💖

okay bestie, welcome to the ZCHKTR(3) page from the Library Functions Manual — yes, the manual name is folded in right here, and we are not copy-pasting that weird header line, periodt 💅✨

🌟 NAME 🌟

The NAME section is literally this path, no cap:

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

✨ SYNOPSIS ✨

Functions/Subroutines

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

🫶 Function/Subroutine Documentation 🫶

Here’s the full signature, served exactly as given — no edits, no “improvements,” bestie:

   subroutine ZCHKTR (logical, dimension( * ) dotype, integer nn, integer,
       dimension( * ) nval, integer nnb, integer, dimension( * ) nbval, integer
       nns, integer, dimension( * ) nsval, double precision thresh, logical
       tsterr, integer nmax, complex*16, dimension( * ) a, complex*16,
       dimension( * ) ainv, complex*16, dimension( * ) b, complex*16,
       dimension( * ) x, complex*16, dimension( * ) xact, complex*16,
       dimension( * ) work, double precision, dimension( * ) rwork, integer
       nout)

and the routine name, once more with feeling: ZCHKTR 💫

🎯 Purpose 🎯

ZCHKTR tests ZTRTRI, -TRS, -RFS, and -CON, and ZLATRS(3) — that’s the whole purpose, iconic and to the point 🎀

🌸 Parameters 🌸

• DOTYPE — DOTYPE is a 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. No plus-one for that type, sorry 💅
• NN — NN is INTEGER; it’s the number of values of N contained in the vector NVAL.
• NVAL — NVAL is an INTEGER array, dimension (NN); these are the values of the matrix column dimension N.
• NNB — NNB is INTEGER; it’s the number of values of NB contained in the vector NBVAL.
• NBVAL — NBVAL is an 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 an INTEGER array, dimension (NNS); these are the values of the number of right hand sides NRHS.
• THRESH — THRESH is DOUBLE PRECISION; 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 — main character behavior 🔥
• TSTERR — TSTERR is LOGICAL; this flag indicates whether error exits are to be tested.
• NMAX — NMAX is INTEGER; it’s the leading dimension of the work arrays, and NMAX >= the maximum value of N in NVAL.
• A — A is a COMPLEX*16 array, dimension (NMAX*NMAX).
• AINV — AINV is a COMPLEX*16 array, dimension (NMAX*NMAX).
• B — B is a COMPLEX*16 array, dimension (NMAX*NSMAX), where NSMAX is the largest entry in NSVAL.
• X — X is a COMPLEX*16 array, dimension (NMAX*NSMAX).
• XACT — XACT is a COMPLEX*16 array, dimension (NMAX*NSMAX).
• WORK — WORK is a COMPLEX*16 array, dimension (NMAX*max(3,NSMAX)).
• RWORK — RWORK is a DOUBLE PRECISION array, dimension (max(NMAX,2*NSMAX)).
• NOUT — NOUT is INTEGER; it’s the unit number for output.

okay that’s the whole page, bestie — final footer sign-off: LAPACK, Version 3.12.0, source/page tag /home/abui...IN/zchktr.f(3) — and the date? The footer you gave doesn’t show one, so we’re not inventing a timestamp, periodt 💅💖🦋
