CCHKHE_AA_2STAGE(3)

Manual name, folded in near the top: Library Functions Manual. Page from the header: /home/abui...aa_2stage.f(3). Okay bestie, this is the Fortran test-routine page for cchkhe_aa_2stage.f(3), and the source path is long enough to need its own snack break. 💅✨

🌸 NAME 🌸

The source file for this page is literally:

/home/abuild/rpmbuild/BUILD/lapack-static-3.12.0-build/lapack-3.12.0/TESTING/LIN/cchkhe_aa_2stage.f

✨ SYNOPSIS ✨

Functions/Subroutines

subroutine CCHKHE_AA_2STAGE (dotype, nn, nval, nnb, nbval, nns, nsval,
    thresh, tsterr, nmax, a, afac, ainv, b, x, xact, work, rwork, iwork,
    nout)
    CCHKHE_AA_2STAGE

💖 Function/Subroutine Documentation 💖

CCHKHE_AA_2STAGE

Full signature, no crumbs left behind:

subroutine CCHKHE_AA_2STAGE (logical, dimension( * ) dotype, integer nn,
    integer, dimension( * ) nval, integer nnb, integer, dimension( * )
    nbval, integer nns, integer, dimension( * ) nsval, real thresh, logical
    tsterr, integer nmax, complex, dimension( * ) a, complex, dimension( * )
    afac, complex, dimension( * ) ainv, complex, dimension( * ) b, complex,
    dimension( * ) x, complex, dimension( * ) xact, complex, dimension( * )
    work, real, dimension( * ) rwork, integer, dimension( * ) iwork, integer
    nout)
    CCHKHE_AA_2STAGE

Purpose

CCHKSY_AA_2STAGE tests CHETRF_AA_2STAGE, -TRS_AA_2STAGE.

Yes, the source says CCHKSY_AA_2STAGE right there in the Purpose block — that is literally what the page has, bestie. I am not out here editing Fortran lore. 🫶

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. 🎀
• 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.
• NNB — NNB is INTEGER. The number of values of NB contained in the vector NBVAL.
• NBVAL — NBVAL is INTEGER array, dimension (NNB). The values of the blocksize NB.
• 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 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.
• TSTERR — TSTERR is LOGICAL. Flag that indicates whether error exits are to be tested.
• NMAX — NMAX is INTEGER. The maximum value permitted for N, used in dimensioning the work arrays.
• A — A is COMPLEX array, dimension (NMAX*NMAX).
• AFAC — AFAC is COMPLEX array, dimension (NMAX*NMAX).
• AINV — AINV is COMPLEX array, dimension (NMAX*NMAX).
• B — B is COMPLEX array, dimension (NMAX*NSMAX) where NSMAX is the largest entry in NSVAL.
• X — X is COMPLEX array, dimension (NMAX*NSMAX).
• XACT — XACT is COMPLEX array, dimension (NMAX*NSMAX).
• WORK — WORK is COMPLEX array, dimension (NMAX*max(3,NSMAX)).
• RWORK — RWORK is REAL array, dimension (max(NMAX,2*NSMAX)).
• IWORK — IWORK is INTEGER array, dimension (2*NMAX).
• NOUT — NOUT is INTEGER. The unit number for output.

Cute sign-off from the footer, bestie: LAPACK — Version 3.12.0 — /home/abui...aa_2stage.f(3). The footer didn’t print a separate date, so I’m not inventing one — periodt. 💜🦋
