SCHKQ3(3)

πŸ“¦ version 3.12.0, in opensuse-leap 16.0

🌸 NAME 🌸

Okay bestie, this is the schkq3.f(3) page from the Library Functions Manual, and the title/header situation is giving truncated-path realness: /home/abui...IN/schkq3.f(3).

The NAME section is literally this source path:

/home/abuild/rpmbuild/BUILD/lapack-static-3.12.0-build/lapack-3.12.0/TESTING/LIN/schkq3.f


✨ SYNOPSIS ✨

🧚 Functions/Subroutines 🧚

The subroutine lineup is:

subroutine SCHKQ3 (dotype, nm, mval, nn, nval, nnb, nbval, nxval,
    thresh, a, copya, s, tau, work, iwork, nout)
    SCHKQ3

πŸ’… Function/Subroutine Documentation πŸ’…

Here’s the full documented signature, bestie β€” exact same energy, no edits:

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

πŸŽ€ Purpose πŸŽ€

The whole assignment is short and iconic: SCHKQ3 tests SGEQP3. That’s the purpose, periodt. πŸ’–

πŸ“ Parameters πŸ“

  • DOTYPE β€” DOTYPE is LOGICAL array, dimension (NTYPES). These are the matrix types 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. Vibe check per matrix type, basically.
  • NM β€” NM is INTEGER. It’s the number of values of M contained in the vector MVAL.
  • MVAL β€” MVAL is INTEGER array, dimension (NM). These are the values of the matrix row dimension M.
  • NN β€” NN is INTEGER. It’s the number of values of N contained in the vector NVAL.
  • NVAL β€” NVAL is INTEGER array, dimension (NN). These are the values of the matrix column dimension N.
  • NNB β€” 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). Pair them up, bestie.
  • NBVAL β€” NBVAL is INTEGER array, dimension (NNB). These are the values of the blocksize NB.
  • NXVAL β€” NXVAL is INTEGER array, dimension (NNB). These are the values of the crossover point NX.
  • THRESH β€” THRESH is REAL. 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. Maximum output mode, no cap.
  • A β€” 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 β€” COPYA is REAL array, dimension (MMAX*NMAX).
  • S β€” S is REAL array, dimension (min(MMAX,NMAX)).
  • TAU β€” TAU is REAL array, dimension (MMAX).
  • WORK β€” WORK is REAL array, dimension (MMAX*NMAX + 4*NMAX + MMAX).
  • IWORK β€” IWORK is INTEGER array, dimension (2*NMAX).
  • NOUT β€” NOUT is INTEGER. It’s the unit number for output.
