ZCHKGT(3)

💖 ZCHKGT(3) 💖

bestie, welcome to the Library Functions Manual — section 3, obviously 💅. This one is literally the page for zchkgt.f in LAPACK, and it is lowkey all about testing. No cap.

🌸 NAME 🌸

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

✨ SYNOPSIS ✨

🎀 Functions/Subroutines

subroutine ZCHKGT (dotype, nn, nval, nns, nsval, thresh, tsterr, a, af,
    b, x, xact, work, rwork, iwork, nout)
    ZCHKGT

🦋 Function/Subroutine Documentation 🦋

💅 subroutine ZCHKGT

okay so the full typed signature is this, exactly:

subroutine ZCHKGT (logical, dimension( * ) dotype, integer nn, integer,
    dimension( * ) nval, integer nns, integer, dimension( * ) nsval, double
    precision thresh, logical tsterr, complex*16, dimension( * ) a,
    complex*16, dimension( * ) af, complex*16, dimension( * ) b, complex*16,
    dimension( * ) x, complex*16, dimension( * ) xact, complex*16,
    dimension( * ) work, double precision, dimension( * ) rwork, integer,
    dimension( * ) iwork, integer nout)
    ZCHKGT

and yes, the routine name is ZCHKGT — main character energy only 👑

🎀 Purpose

ZCHKGT tests ZGTTRF, -TRS, -RFS, and -CON

that's the whole vibe check: it tests those four, periodt ✨

🧚 Parameters

• DOTYPE — DOTYPE is 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. 🫶
• NN — NN is INTEGER. The number of values of N contained in the vector NVAL.
• NVAL — NVAL is INTEGER array, dimension (NN). The values of the matrix dimension N.
• NNS — NNS is INTEGER. The number of values of NRHS contained in the vector NSVAL.
• NSVAL — NSVAL is INTEGER array, dimension (NNS). The values of the number of right hand sides NRHS.
• THRESH — THRESH is 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 — TSTERR is LOGICAL. Flag that indicates whether error exits are to be tested.
• A — A is COMPLEX*16 array, dimension (NMAX*4).
• AF — AF is COMPLEX*16 array, dimension (NMAX*4).
• B — B is COMPLEX*16 array, dimension (NMAX*NSMAX) where NSMAX is the largest entry in NSVAL.
• X — X is COMPLEX*16 array, dimension (NMAX*NSMAX).
• XACT — XACT is COMPLEX*16 array, dimension (NMAX*NSMAX).
• WORK — WORK is COMPLEX*16 array, dimension (NMAX*max(3,NSMAX)).
• RWORK — RWORK is DOUBLE PRECISION array, dimension (max(NMAX)+2*NSMAX).
• IWORK — IWORK is INTEGER array, dimension (NMAX).
• NOUT — NOUT is INTEGER. The unit number for output.
