TESTING/LIN/schkq3.f(3)

🌸 NAME 🌸

okay bestie, you're on TESTING/LIN/schkq3.f(3) — yes, that's the page name, and it's serving Library Functions Manual energy. The file is TESTING/LIN/schkq3.f, and the whole page is about SCHKQ3, which tests SGEQP3. ✨

🌈 SYNOPSIS 🌈

🧚 Functions/Subroutines 🧚

• subroutine schkq3 — the routine in question, with this exact call shape:

subroutine schkq3 (dotype, nm, mval, nn, nval, nnb, nbval, nxval,
           thresh, a, copya, s, tau, work, iwork, nout)

💖 Function/Subroutine Documentation 💖

Full typed signature, every type and dimension accounted for, no cap:

subroutine schkq3 (logical, dimension( * ) dotype, integer nm, integer,
     dimension( * ) mval, integer nn, integer, dimension( * ) nval, integer
     nnb, integer, dimension( * ) nbval, integer, dimension( * ) nxval, real
     thresh, real, dimension( * ) a, real, dimension( * ) copya, real,
     dimension( * ) s, real, dimension( * ) tau, real, dimension( * ) work,
     integer, dimension( * ) iwork, integer nout)

SCHKQ3 — that's the name, and it's iconic. 💅

✨ Purpose ✨

SCHKQ3 tests SGEQP3. That's it, that's the purpose, 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.
• 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.
• THRESH — THRESH is REAL. 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 REAL 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 REAL array, dimension (MMAX*NMAX).
• S — S is REAL array, dimension (min(MMAX,NMAX)).
• TAU — TAU is REAL array, dimension (MMAX).
• WORK — WORK is REAL array, dimension (MMAX*NMAX + 4*NMAX + MMAX).
• IWORK — IWORK is INTEGER array, dimension (2*NMAX).
• NOUT — NOUT is INTEGER. The unit number for output.
