TESTING/LIN/zdrvsy_aa.f(3)

💅 TESTING/LIN/zdrvsy_aa.f

okay so bestie, this is a page straight out of the LAPACK docs — <pink>Library Functions Manual</pink> vibes, and the star of the show is a little Fortran file called TESTING/LIN/zdrvsy_aa.f. she's a tester, she's thorough, and she's about to walk you through it 🎀

✨ SYNOPSIS ✨

🌸 Functions/Subroutines

• subroutine zdrvsy_aa (dotype, nn, nval, nrhs, thresh, tsterr, nmax, a, afac, ainv, b, x, xact, work, rwork, iwork, nout) — ZDRVSY_AA

🦋 Function/Subroutine Documentation 🦋

💜 subroutine zdrvsy_aa

here's the full signature, copied exactly so you can trust it, no cap:

subroutine zdrvsy_aa (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 👑 (seriously, that's the whole line)

⭐ Purpose:

!>
!> ZDRVSY_AA tests the driver routine ZSYSV_AA.
!>

periodt. her only job is testing ZSYSV_AA and she does it well 💅

🎀 Parameters

• DOTYPE — DOTYPE is LOGICAL array, dimension (NTYPES). these are the matrix types to be used for testing, bestie. matrices of type j (for 1 <= j <= NTYPES) get tested if DOTYPE(j) = .TRUE. — but if DOTYPE(j) = .FALSE., then type j is simply not used. no drama, just skipped 🙈
• NN — NN is INTEGER. it's the number of values of N contained in the vector NVAL. slay 🌸
• NVAL — NVAL is INTEGER array, dimension (NN). these are the values of the matrix dimension N. literally the sizes, iconically 💖
• NRHS — NRHS is INTEGER. the number of right hand side vectors to be generated for each linear system. that's a lot of right-hand sides, and honestly? ate ✨
• THRESH — THRESH is COMPLEX*16. it's the threshold value for the test ratios. a result gets included in the output file if RESULT >= THRESH. and if you want every test ratio printed? use THRESH = 0. no filter, main character energy 🔥
• 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. she's the ceiling, the limit, the moment 💅
• 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*NRHS). 🍓
• X — X is COMPLEX*16 array, dimension (NMAX*NRHS). ⭐
• XACT — XACT is COMPLEX*16 array, dimension (NMAX*NRHS). 💜
• WORK — WORK is COMPLEX*16 array, dimension (NMAX*max(2,NRHS)). note the max(2,NRHS), iykyk 🧚
• RWORK — RWORK is COMPLEX*16 array, dimension (NMAX+2*NRHS). (yes, the original says COMPLEX*16 for RWORK — that's exactly what it says, so that's exactly what we're giving you, no edits 💀)
• IWORK — IWORK is INTEGER array, dimension (2*NMAX). 🌸
• NOUT — NOUT is INTEGER. the unit number for output. where the receipts get printed, fr fr 🎀
