TESTING/LIN/zchktp.f(3)

🌸 NAME 🌸

Okay so this is the Library Functions Manual page for TESTING/LIN/zchktp.f(3) — the zchktp subroutine's little home. The actual file is TESTING/LIN/zchktp.f. Slay.

✨ SYNOPSIS ✨

Functions/Subroutines

• subroutine zchktp (dotype, nn, nval, nns, nsval, thresh, tsterr, nmax, ap, ainvp, b, x, xact, work, rwork, nout) — bestie, this is ZCHKTP in all her main character glory.

💅 Function/Subroutine Documentation 💅

subroutine zchktp

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 — that's the name, no cap.

🎯 Purpose

okay so ZCHKTP tests ZTPTRI, -TRS, -RFS, and -CON, and ZLATPS. Literally her whole job. Periodt.

💖 Parameters

• DOTYPE — LOGICAL array, dimension (NTYPES). The matrix types to be used for testing. 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. iykyk.
• 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). That's it. Iconic.
• AINVP — COMPLEX*16 array, dimension (NMAX*(NMAX+1)/2). Also iconic.
• 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.
