TESTING/LIN/zchkql.f(3)

🎀 NAME 🎀

TESTING/LIN/zchkql.f — okay bestie, this is the TESTING/LIN/zchkql.f(3) page from the Library Functions Manual, and it's the whole saga of the zchkql testing routine. It's giving "I test factorization routines for LAPACK" main character energy. 💅

✨ SYNOPSIS ✨

💫 Functions/Subroutines

• subroutine zchkql — the call signature, literally every arg included:

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

• ZCHKQL — the routine name, periodt 🫶

🎯 Purpose:

ZCHKQL tests ZGEQLF, ZUNGQL and ZUNMQL. That's the purpose, and she ate. ✨

🧸 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. 💜
• 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). 🎀
• 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. 🔥
• 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). ✨
• AL — AL 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). 💜
• NOUT — NOUT is INTEGER. The unit number for output. 🎀
