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

okay bestie, this is a page from the Library Functions Manual and it's literally all about one little Fortran file with a very long address, so let's get into it 🎀

✨ SYNOPSIS ✨

🌸 Functions/Subroutines 🌸

• subroutine DDRVSY_AA (dotype, nn, nval, nrhs, thresh, tsterr, nmax, a, afac, ainv, b, x, xact, work, rwork, iwork, nout) — DDRVSY_AA (yes that's the whole description, she's mysterious like that 💅)

🦋 Function/Subroutine Documentation 🦋

🌈 the full signature, no cap 🌈

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

💖 Purpose 💖

!> !> DDRVSY_AA tests the driver routine DSYSV_AA. !>

like literally that's her job: she tests DSYSV_AA. main character behavior honestly 👑

🎀 Parameters 🎀

• DOTYPE — DOTYPE is a LOGICAL array, dimension (NTYPES). It's the guest list basically: matrix types to be used for testing, and matrices of type j (for 1 <= j <= NTYPES) get used for testing if DOTYPE(j) = .TRUE.; if DOTYPE(j) = .FALSE., then type j is not used. no invite, no entry 🚫
• NN — NN is INTEGER. It's the number of values of N contained in the vector NVAL. she's the count, she counts 💅
• NVAL — NVAL is an INTEGER array, dimension (NN). These are the values of the matrix dimension N. the vibes of sizes, basically ✨
• NRHS — NRHS is INTEGER. The number of right hand side vectors to be generated for each linear system. many right hands, much slay 🫶
• THRESH — THRESH is DOUBLE PRECISION. The threshold value for the test ratios. A result is included in the output file if RESULT >= THRESH. Wanna have every single test ratio printed? Use THRESH = 0. literally all of them, no filter 🔥
• TSTERR — TSTERR is LOGICAL. Flag that indicates whether error exits are to be tested. are we testing the messy exits? yes ma'am 🚪
• NMAX — NMAX is INTEGER. The maximum value permitted for N, used in dimensioning the work arrays. the ceiling, the limit, the final boss of sizing 👑
• A — A is a DOUBLE PRECISION array, dimension (NMAX*NMAX). iconic, no notes 💜
• AFAC — AFAC is a DOUBLE PRECISION array, dimension (NMAX*NMAX). also iconic 💜
• AINV — AINV is a DOUBLE PRECISION array, dimension (NMAX*NMAX). still iconic 💜
• B — B is a DOUBLE PRECISION array, dimension (NMAX*NRHS). the B in question 🍓
• X — X is a DOUBLE PRECISION array, dimension (NMAX*NRHS). 🦋
• XACT — XACT is a DOUBLE PRECISION array, dimension (NMAX*NRHS). the exact one, she's precise like that ✨
• WORK — WORK is a DOUBLE PRECISION array, dimension (NMAX*max(2,NRHS)). ok her dimension has a max() in it and that's honestly so her 💅
• RWORK — RWORK is a DOUBLE PRECISION array, dimension (NMAX+2*NRHS). the R stands for real ones only 🌸
• IWORK — IWORK is an INTEGER array, dimension (2*NMAX). integers, but make it fashion 🎀
• NOUT — NOUT is INTEGER. The unit number for output. where the receipts get printed 📬
