💅 TESTING/LIN/zchkqp3rk.f — Library Functions Manual 💅

okay so bestie, this is the manual page for TESTING/LIN/zchkqp3rk.f, from the Library Functions Manual. It’s giving ZCHKQP3RK testing-routine energy, and we’re getting into all of it. ✨

🌸 NAME 🌸

TESTING/LIN/zchkqp3rk.f

✨ SYNOPSIS ✨

Functions/Subroutines

• subroutine zchkqp3rk — the signature is right here, character for character:

subroutine zchkqp3rk (dotype, nm, mval, nn, nval, nns, nsval, nnb,
    nbval, nxval, thresh, a, copya, b, copyb, s, tau, work, rwork,
    iwork, nout)

ZCHKQP3RK — yup, that’s the routine name. 💖

🧚 Function/Subroutine Documentation 🧚

Here’s the full typed-out signature:

subroutine zchkqp3rk (logical, dimension( * ) dotype, integer nm, integer,
    dimension( * ) mval, integer nn, integer, dimension( * ) nval, integer
    nns, integer, dimension( * ) nsval, integer nnb, integer, dimension( * )
    nbval, integer, dimension( * ) nxval, double precision thresh,
    complex*16, dimension( * ) a, complex*16, dimension( * ) copya,
    complex*16, dimension( * ) b, complex*16, dimension( * ) copyb, double
    precision, dimension( * ) s, complex*16, dimension( * ) tau, complex*16,
    dimension( * ) work, double precision, dimension( * ) rwork, integer,
    dimension( * ) iwork, integer nout)

ZCHKQP3RK — again, iconic. 👑

🎀 Purpose 🎀

!>
!> ZCHKQP3RK tests ZGEQP3RK.

No cap: ZCHKQP3RK tests ZGEQP3RK. That’s the whole purpose block, preserved. 🫶

🌈 Parameters 🌈

• DOTYPE — DOTYPE is LOGICAL array, dimension (NTYPES). It’s 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. It’s the number of values of M contained in the vector MVAL.
• MVAL — MVAL is INTEGER array, dimension (NM). These are the values of the matrix row dimension M.
• NN — NN is INTEGER. It’s the number of values of N contained in the vector NVAL.
• NVAL — NVAL is INTEGER array, dimension (NN). These are the values of the matrix column dimension N.
• NNS — NNS is INTEGER. It’s the number of values of NRHS contained in the vector NSVAL.
• NSVAL — NSVAL is INTEGER array, dimension (NNS). These are the values of the number of right hand sides NRHS.
• NNB — NNB is INTEGER. It’s 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). These are the values of the blocksize NB.
• NXVAL — NXVAL is INTEGER array, dimension (NNB). These are the values of the crossover point NX.
• THRESH — THRESH is DOUBLE PRECISION. It’s 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.
• 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).
• B — B is COMPLEX*16 array, dimension (MMAX*NSMAX) where MMAX is the maximum value of M in MVAL and NSMAX is the maximum value of NRHS in NSVAL.
• COPYB — COPYB is COMPLEX*16 array, dimension (MMAX*NSMAX).
• 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 (max(M*max(M,N) + 4*min(M,N) + max(M,N))).
• RWORK — RWORK is DOUBLE PRECISION array, dimension (4*NMAX).
• IWORK — IWORK is INTEGER array, dimension (2*NMAX).
• NOUT — NOUT is INTEGER. It’s the unit number for output.
