🎀 NAME 🎀

TESTING/LIN/zchkhe_aa_2stage.f — yup bestie, that's the page. It lives in the Library Functions Manual, and the page title vibe is TESTING/LI...a_2stage.f(3). LAPACK testing content, no cap.

💖 Function/Subroutine Documentation 💖

subroutine zchkhe_aa_2stage (logical, dimension( * ) dotype, integer nn,
    integer, dimension( * ) nval, integer nnb, integer, dimension( * )
    nbval, integer nns, integer, dimension( * ) nsval, double precision
    thresh, logical tsterr, integer nmax, complex*16, dimension( * ) a,
    complex*16, dimension( * ) afac, complex*16, dimension( * ) ainv,

    ZCHKHE_AA_2STAGE

🌸 Purpose 🌸

The source literally says this inside its !> doc-comment, so here it is exactly:

!>
!> ZCHKSY_AA_2STAGE tests ZHETRF_AA_2STAGE, -TRS_AA_2STAGE.
!>

👀 Note the spelling in that purpose line: it says ZCHKSY_AA_2STAGE, not ZCHKHE_AA_2STAGE. I'm not editing the source, bestie — I'm just telling you what it says.

🦋 Parameters 🦋

• DOTYPE — 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. Periodt.
• 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 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.
• 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*16 array, dimension (NMAX*NMAX).
• AFAC — AFAC is COMPLEX*16 array, dimension (NMAX*NMAX).
• AINV — AINV is COMPLEX*16 array, dimension (NMAX*NMAX).
• B — B is COMPLEX*16 array, dimension (NMAX*NSMAX) where NSMAX is the largest entry in NSVAL.
• X — X is COMPLEX*16 array, dimension (NMAX*NSMAX).
• XACT — XACT is COMPLEX*16 array, dimension (NMAX*NSMAX).
• WORK — WORK is COMPLEX*16 array, dimension (NMAX*max(3,NSMAX)).
• RWORK — RWORK is DOUBLE PRECISION array, dimension (max(NMAX,2*NSMAX)).
• IWORK — IWORK is INTEGER array, dimension (2*NMAX).
• NOUT — NOUT is INTEGER. The unit number for output.

💖 okay bestie, that's the whole page! Source/version: LAPACK Version 3.12.0, page TESTING/LI...a_2stage.f(3). The footer doesn't show a date, so I'm not inventing one — it just ends with Generated automatically by Doxygen for LAPACK from the source code. Slay. 🎀✨
