TESTING/LIN/zdrvhe_aa.f(3)

🦋 okay so this is the TESTING/LIN/zdrvhe_aa.f page, Library Functions Manual, section (3) 🦋

bestie, we are deep in the LAPACK testing zone and it’s giving “Fortran subroutine character development” 💅 no cap.

🌸 NAME 🌸

TESTING/LIN/zdrvhe_aa.f

---

✨ SYNOPSIS ✨

🦋 Functions/Subroutines 🦋

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

---

💅 Function/Subroutine Documentation 💅

okay so here’s the whole signature, literally character-for-character, because we do not play about Fortran declarations 🫶

subroutine zdrvhe_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)
    ZDRVHE_AA

🎀 Purpose 🎀

okay so the main-character job of ZDRVHE_AA is this: it tests the driver routine ZHESV_AA. that’s the tea. ZDRVHE_AA tests the driver routine ZHESV_AA. periodt 💖

🍓 Parameters 🍓

• DOTYPE — it’s a LOGICAL array, dimension (NTYPES). these are the matrix types used for testing. 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. bestie, it’s a whole invite list for matrix types 💌
• NN — it’s an INTEGER. this is the number of values of N contained in the vector NVAL.
• NVAL — it’s an INTEGER array, dimension (NN). these are the values of the matrix dimension N.
• NRHS — it’s an INTEGER. this is the number of right hand side vectors to be generated for each linear system. yes, plural vectors, we contain multitudes ✨
• THRESH — it’s a DOUBLE PRECISION. this is the threshold value for the test ratios. a result is included in the output file if RESULT >= THRESH. if you want every test ratio printed, use THRESH = 0. like, every single one. no filter, no chill 😭
• TSTERR — it’s a LOGICAL. this flag indicates whether error exits are to be tested.
• NMAX — it’s an INTEGER. this is the maximum value permitted for N, and it’s used in dimensioning the work arrays. lowkey the size-limit main character.
• A — it’s a COMPLEX*16 array, dimension (NMAX*NMAX).
• AFAC — it’s a COMPLEX*16 array, dimension (NMAX*NMAX).
• AINV — it’s a COMPLEX*16 array, dimension (NMAX*NMAX).
• B — it’s a COMPLEX*16 array, dimension (NMAX*NRHS).
• X — it’s a COMPLEX*16 array, dimension (NMAX*NRHS).
• XACT — it’s a COMPLEX*16 array, dimension (NMAX*NRHS).
• WORK — it’s a COMPLEX*16 array, dimension (NMAX*max(2,NRHS)).
• RWORK — it’s a DOUBLE PRECISION array, dimension (NMAX+2*NRHS).
• IWORK — it’s an INTEGER array, dimension (NMAX).
• NOUT — it’s an INTEGER. this is the unit number for output. the output goes here, bestie 🫶

okay bestie, that’s the whole page 💖 source/version sign-off: this is from LAPACK, Version 3.12.0, and the footer also says TESTING/LIN/zdrvhe_aa.f(3). date? not listed in the footer, so I’m not inventing one 🙈. bye, slay, and may your test ratios always be above threshold ✨💅🫶
