TESTING/LI...a_2stage.f(3)

okay so bestie, welcome to the TESTING/LI...a_2stage.f(3) page from the Library Functions Manual — it’s the LAPACK testing page for TESTING/LIN/zdrvsy_aa_2stage.f and it’s giving very specific numerical tea 💅✨.

NAME 🌸

TESTING/LIN/zdrvsy_aa_2stage.f

SYNOPSIS ✨

Functions/Subroutines 🎀

subroutine zdrvsy_aa_2stage (dotype, nn, nval, nrhs, thresh, tsterr,
    nmax, a, afac, ainv, b, x, xact, work, rwork, iwork, nout)
    ZDRVSY_AA_2STAGE

Function/Subroutine Documentation 💖

subroutine zdrvsy_aa_2stage (logical, dimension( * ) dotype, integer nn,
    integer, dimension( * ) nval, integer nrhs, double precision thresh,
    logical tsterr, integer nmax, complex*16, dimension( * ) a, complex*16,
    dimension( * ) afac, complex*16, dimension( * ) ainv, complex*16,
    dimension( * ) b, complex*16, dimension( * ) x, complex*16, dimension( *
    ) xact, complex*16, dimension( * ) work, double precision, dimension( *
    ) rwork, integer, dimension( * ) iwork, integer nout)
    ZDRVSY_AA_2STAGE

This routine is ZDRVSY_AA_2STAGE, and yes, the name is a whole mouthful — we still love her 👑.

Purpose 🦋

The whole job is this: ZDRVSY_AA_2STAGE tests the driver routine ZSYSV_AA_2STAGE. That’s the main character assignment, periodt 💫.

Parameters 🎀

• DOTYPE — DOTYPE is a LOGICAL array, dimension (NTYPES). It says which matrix types get 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 an INTEGER array, dimension (NN). The values of the matrix dimension N.
• NRHS — NRHS is INTEGER. The number of right hand side vectors to be generated for each linear system.
• 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 a COMPLEX*16 array, dimension (NMAX*NMAX).
• AFAC — AFAC is a COMPLEX*16 array, dimension (NMAX*NMAX).
• AINV — AINV is a COMPLEX*16 array, dimension (NMAX*NMAX).
• B — B is a COMPLEX*16 array, dimension (NMAX*NRHS).
• X — X is a COMPLEX*16 array, dimension (NMAX*NRHS).
• XACT — XACT is a COMPLEX*16 array, dimension (NMAX*NRHS).
• WORK — WORK is a COMPLEX*16 array, dimension (NMAX*max(2,NRHS)).
• RWORK — RWORK is a COMPLEX*16 array, dimension (NMAX+2*NRHS). Yep, that’s what this parameter blurb says, bestie — we keep the page’s exact words 🫶.
• IWORK — IWORK is an INTEGER array, dimension (NMAX).
• NOUT — NOUT is INTEGER. The unit number for output.

okay that’s the whole page, bestie 💜 — cute sign-off with the footer deets: source/version is LAPACK, Version 3.12.0, and the footer tag is TESTING/LI...a_2stage.f(3); no separate calendar date is shown beyond that tag. byeee 🫶✨
