DCHKPT(3)

💖 NAME 💖

Hiii bestie!! Welcome to the DCHKPT(3) page — you're in the Library Functions Manual, and the main-character energy is coming from /home/abuild/rpmbuild/BUILD/lapack-static-3.12.0-build/lapack-3.12.0/TESTING/LIN/dchkpt.f. That's literally the NAME section: a whole file path serving full realness 💅

✨ SYNOPSIS ✨

Functions/Subroutines

subroutine DCHKPT (dotype, nn, nval, nns, nsval, thresh, tsterr, a, d,
           e, b, x, xact, work, rwork, nout)
           DCHKPT

🧚 FUNCTION/SUBROUTINE DOCUMENTATION 🧚

subroutine DCHKPT (logical, dimension( * ) dotype, integer nn, integer,
       dimension( * ) nval, integer nns, integer, dimension( * ) nsval, double
       precision thresh, logical tsterr, double precision, dimension( * ) a,
       double precision, dimension( * ) d, double precision, dimension( * ) e,
       double precision, dimension( * ) b, double precision, dimension( * ) x,

       work, double precision, dimension( * ) rwork, integer nout)

DCHKPT

🌸 Purpose 🌸

The purpose, straight from the source, is:

!>
!> DCHKPT tests DPTTRF, -TRS, -RFS, and -CON
!>

So she's the test queen for DPTTRF, -TRS, -RFS, and -CON. Obsessed, honestly 💖

🎀 Parameters 🎀

Okay bestie, here's the full parameter lineup — every single one, no skipping:

• 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. 💅
• 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 dimension N.
• NNS — NNS is INTEGER. The number of values of NRHS contained in the vector NSVAL.
• NSVAL — NSVAL is INTEGER array, dimension (NNS). The values of the number of right hand sides NRHS.
• 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. No cap, that's the rule ✨
• TSTERR — TSTERR is LOGICAL. Flag that indicates whether error exits are to be tested.
• A — A is DOUBLE PRECISION array, dimension (NMAX*2).
• D — D is DOUBLE PRECISION array, dimension (NMAX*2).
• E — E is DOUBLE PRECISION array, dimension (NMAX*2).
• B — B is DOUBLE PRECISION array, dimension (NMAX*NSMAX) where NSMAX is the largest entry in NSVAL.
• X — X is DOUBLE PRECISION array, dimension (NMAX*NSMAX).
• XACT — XACT is DOUBLE PRECISION array, dimension (NMAX*NSMAX).
• WORK — WORK is DOUBLE PRECISION array, dimension (NMAX*max(3,NSMAX)).
• RWORK — RWORK is DOUBLE PRECISION array, dimension (max(NMAX,2*NSMAX)).
• NOUT — NOUT is INTEGER. The unit number for output.

Okay that's the whole page, bestie — LAPACK Version 3.12.0, from /home/abui...IN/dchkpt.f(3) in the footer, and the footer didn't hand me a date to hype, so I'm not inventing one 💀 Byeee, go test those routines! 💅💖✨
