TESTING/LIN/zchkrq.f(3)

🎀 NAME 🎀

Okay bestie, this is the TESTING/LIN/zchkrq.f(3) page from the Library Functions Manual. It’s the home of zchkrq, and it’s lowkey here to test some RQ routines — details below, no cap 💅.

✨ SYNOPSIS ✨

🌸 Functions/Subroutines 🌸

       subroutine zchkrq (dotype, nm, mval, nn, nval, nnb, nbval, nxval, nrhs,
           thresh, tsterr, nmax, a, af, aq, ar, ac, b, x, xact, tau, work,
           rwork, iwork, nout)
           ZCHKRQ

       nnb, integer, dimension( * ) nbval, integer, dimension( * ) nxval,
       integer nrhs, double precision thresh, logical tsterr, integer nmax,

       ZCHKRQ

💖 Purpose 💖

Bestie, ZCHKRQ tests ZGERQF, ZUNGRQ and ZUNMRQ. That’s the whole vibe of this one ✨.

🫶 Parameters 🫶

• DOTYPE — DOTYPE is LOGICAL array, dimension (NTYPES). It’s 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. Periodt 💅.
• NM — NM is INTEGER. The number of values of M contained in the vector MVAL. Slay, simple.
• 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.
• NNB — NNB is INTEGER. The number of values of NB and NX contained in the vectors NBVAL and NXVAL. The blocking parameters are used in pairs (NB,NX). Iconic little duo, fr fr.
• NBVAL — NBVAL is INTEGER array, dimension (NNB). The values of the blocksize NB.
• NXVAL — NXVAL is INTEGER array, dimension (NNB). The values of the crossover point NX.
• NRHS — NRHS is INTEGER. The number of right hand side vectors to be generated for each linear system.
• 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. Literally all the tea, no filter.
• TSTERR — TSTERR is LOGICAL. Flag that indicates whether error exits are to be tested.
• NMAX — NMAX is INTEGER. The maximum value permitted for M or N, used in dimensioning the work arrays.
• A — A is COMPLEX*16 array, dimension (NMAX*NMAX).
• AF — AF is COMPLEX*16 array, dimension (NMAX*NMAX).
• AQ — AQ is COMPLEX*16 array, dimension (NMAX*NMAX).
• AR — AR is COMPLEX*16 array, dimension (NMAX*NMAX).
• AC — AC is COMPLEX*16 array, dimension (NMAX*NMAX).
• B — B is COMPLEX*16 array, dimension (NMAX*NRHS).
• X — X is COMPLEX*16 array, dimension (NMAX*NRHS).
• XACT — XACT is COMPLEX*16 array, dimension (NMAX*NRHS).
• TAU — TAU is COMPLEX*16 array, dimension (NMAX).
• WORK — WORK is COMPLEX*16 array, dimension (NMAX*NMAX).
• RWORK — RWORK is DOUBLE PRECISION array, dimension (NMAX).
• IWORK — IWORK is INTEGER array, dimension (NMAX).
• NOUT — NOUT is INTEGER. The unit number for output.
