ZCHKTP(3)

okay bestie, this is the zchktp.f(3) page from the Library Functions Manual, and yes it’s a LAPACK test-routine page. grab your iced coffee, we’re reading the whole thing. 💅✨

🌸 NAME 🌸

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

that’s the file this entry is for. no cap, that’s the whole NAME section. 🫶

✨ SYNOPSIS ✨

🦋 Functions/Subroutines 🦋

here’s the callable vibe:

       subroutine ZCHKTP (dotype, nn, nval, nns, nsval, thresh, tsterr, nmax,
           ap, ainvp, b, x, xact, work, rwork, nout)
           ZCHKTP

---

🧚 Function/Subroutine Documentation 🧚

   subroutine ZCHKTP (logical, dimension( * ) dotype, integer nn, integer,
       dimension( * ) nval, integer nns, integer, dimension( * ) nsval, double
       precision thresh, logical tsterr, integer nmax, complex*16, dimension( *
       ) ap, complex*16, dimension( * ) ainvp, complex*16, dimension( * ) b,
       complex*16, dimension( * ) x, complex*16, dimension( * ) xact,
       complex*16, dimension( * ) work, double precision, dimension( * ) rwork,
       integer nout)
       ZCHKTP

🎯 Purpose 🎯

this one is the test queen for ZTPTRI, -TRS, -RFS, and -CON, and ZLATPS. that’s the purpose, and it ate. 💅

💅 Parameters 💅

• DOTYPE — LOGICAL array, dimension (NTYPES). this is the matrix-type mood board. 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.
• 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 — DOUBLE PRECISION. 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.
• AP — COMPLEX*16 array, dimension (NMAX*(NMAX+1)/2).
• AINVP — COMPLEX*16 array, dimension (NMAX*(NMAX+1)/2).
• B — COMPLEX*16 array, dimension (NMAX*NSMAX) where NSMAX is the largest entry in NSVAL.
• X — COMPLEX*16 array, dimension (NMAX*NSMAX).
• XACT — COMPLEX*16 array, dimension (NMAX*NSMAX).
• WORK — COMPLEX*16 array, dimension (NMAX*max(3,NSMAX)).
• RWORK — DOUBLE PRECISION array, dimension (max(NMAX,2*NSMAX)).
• NOUT — INTEGER. the unit number for output.

XOXO 💖 — this is LAPACK Version 3.12.0, footer source /home/abui...IN/zchktp.f(3) (the full path is up in NAME), and the footer didn’t list a date, so I’m not inventing one. periodt. 🫶
