TESTING/LIN/zchktz.f(3)

💖 NAME 💖

Okay bestie, welcome to TESTING/LIN/zchktz.f — the Library Functions Manual page for the subroutine zchktz, aka ZCHKTZ. It’s giving “I test ZTZRZF” energy, and honestly? Very main character. ✨

✨ SYNOPSIS ✨

💅 Functions/Subroutines 💅

subroutine zchktz (dotype, nm, mval, nn, nval, thresh, tsterr, a, copya,
           s, tau, work, rwork, nout)
           ZCHKTZ

🧚 Function/Subroutine Documentation 🧚

Here’s the full signature, no crumbs:

subroutine zchktz (logical, dimension( * ) dotype, integer nm, integer,
       dimension( * ) mval, integer nn, integer, dimension( * ) nval, double
       precision thresh, logical tsterr, complex*16, dimension( * ) a,
       complex*16, dimension( * ) copya, double precision, dimension( * ) s,
       complex*16, dimension( * ) tau, complex*16, dimension( * ) work, double
       precision, dimension( * ) rwork, integer nout)
       ZCHKTZ

🎯 Purpose

ZCHKTZ tests ZTZRZF. That’s the whole purpose, and honestly? Iconic. 💅

🌸 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. 🫶
• NM — NM is INTEGER. The number of values of M contained in the vector MVAL.
• MVAL — MVAL is INTEGER array, dimension (NM). The values of the matrix row dimension M.
• 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 column dimension N.
• 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 (MMAX*NMAX) where MMAX is the maximum value of M in MVAL and NMAX is the maximum value of N in NVAL.
• COPYA — COPYA is COMPLEX*16 array, dimension (MMAX*NMAX).
• S — S is DOUBLE PRECISION array, dimension (min(MMAX,NMAX)).
• TAU — TAU is COMPLEX*16 array, dimension (MMAX).
• WORK — WORK is COMPLEX*16 array, dimension (MMAX*NMAX + 4*NMAX + MMAX).
• RWORK — RWORK is DOUBLE PRECISION array, dimension (2*NMAX).
• NOUT — NOUT is INTEGER. The unit number for output.
