DCHKPS(3)

💅 NAME

okay so this file is literally /home/abuild/rpmbuild/BUILD/lapack-static-3.12.0-build/lapack-3.12.0/TESTING/LIN/dchkps.f bestie, and it's living in the Library Functions Manual section (that's (3) for the uninitiated 🫶).

✨ SYNOPSIS

Functions/Subroutines

subroutine DCHKPS (dotype, nn, nval, nnb, nbval, nrank, rankval, thresh,
    tsterr, nmax, a, afac, perm, piv, work, rwork, nout)

DCHKPS — that's the whole vibe, she's the name and the function 💖

DCHKPS 🔥 (yes she said it twice, she contains multitudes)

🌸 Purpose

!> !> DCHKPS tests DPSTRF. !>

no cap, that's the whole job — she tests DPSTRF and she does it flawlessly 👑

💜 Parameters

• DOTYPE — DOTYPE is LOGICAL array, dimension (NTYPES)</p> — the matrix types to be used for testing. Matrices of type j (for 1 <= j <= NTYPES) get tested if DOTYPE(j) = .TRUE.; if DOTYPE(j) = .FALSE., then type j is literally not used, periodt.
• NN — NN is INTEGER</p> — the number of values of N chillin' in the vector NVAL.
• NVAL — NVAL is INTEGER array, dimension (NN)</p> — the values of the matrix dimension N. the icons 💅
• NNB — NNB is INTEGER</p> — the number of values of NB contained in the vector NBVAL.
• NBVAL — NBVAL is INTEGER array, dimension (NNB)</p> — the values of the block size NB.
• NRANK — NRANK is INTEGER</p> — the number of values of RANK contained in the vector RANKVAL.
• RANKVAL — RANKVAL is INTEGER array, dimension (NBVAL)</p> — the values of the block size NB. (that's what the page says, bestie, and we do not editorialize 💀 we just report it exactly)
• THRESH — THRESH is DOUBLE PRECISION</p> — the threshold value for the test ratios. A result gets included in the output file if RESULT >= THRESH. Wanna see every single test ratio printed? use THRESH = 0 🫶
• TSTERR — TSTERR is LOGICAL</p> — flag that indicates whether error exits are to be tested.
• NMAX — NMAX is INTEGER</p> — the maximum value permitted for N, used in dimensioning the work arrays. she's the ceiling fr fr.
• A — A is DOUBLE PRECISION array, dimension (NMAX*NMAX)</p>
• AFAC — AFAC is DOUBLE PRECISION array, dimension (NMAX*NMAX)</p>
• PERM — PERM is DOUBLE PRECISION array, dimension (NMAX*NMAX)</p>
• PIV — PIV is INTEGER array, dimension (NMAX)</p>
• WORK — WORK is DOUBLE PRECISION array, dimension (NMAX*3)</p>
• RWORK — RWORK is DOUBLE PRECISION array, dimension (NMAX)</p>
• NOUT — NOUT is INTEGER</p> — the unit number for output. where the receipts get printed 📬
