TESTING/LIN/zdrvhp.f(3)

okay so this is TESTING/LIN/zdrvhp.f(3), straight out of the Library Functions Manual, and it’s giving ✨ LAPACK test-driver energy ✨. bestie, we are about to read the whole thing, no skips, no cap 💅

---

🌸 NAME 🌸

TESTING/LIN/zdrvhp.f — that’s the whole NAME section, and honestly? iconic minimalism 🎀

🦋 SYNOPSIS 🦋

✨ Functions/Subroutines ✨

the subroutine in question is literally this:

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

🧚 Function/Subroutine Documentation 🧚

okay so here’s the full signature with all the types and dimensions, copied exactly because we do not mess with Fortran signatures, periodt:

subroutine zdrvhp (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)
       ZDRVHP

💖 Purpose 💖

ZDRVHP tests the driver routines ZHPSV and -SVX. that’s the whole purpose, and she said it with her chest 💅✨

🎀 Parameters 🎀

• DOTYPE — DOTYPE is LOGICAL array, dimension (NTYPES). the matrix types to be 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. so basically it’s the yes/no list for which matrix types get invited to the test party 🎟️
• NN — NN is INTEGER. the number of values of N contained in the vector NVAL. she’s counting the N-values, lowkey important 🔢
• NVAL — NVAL is INTEGER array, dimension (NN). the values of the matrix dimension N. these are the actual N values, fr fr 🦋
• NRHS — NRHS is INTEGER. the number of right hand side vectors to be generated for each linear system. right-hand-side vectors, plural, we love to see it 🫶
• 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. bestie, 0 means show me everything 👀
• TSTERR — TSTERR is LOGICAL. flag that indicates whether error exits are to be tested. error exits: are we testing them or not? that’s the vibe check 🚦
• NMAX — NMAX is INTEGER. the maximum value permitted for N, used in dimensioning the work arrays. she’s the ceiling for N and the reason the work arrays know their size 🏛️
• A — A is COMPLEX*16 array, dimension (NMAX*(NMAX+1)/2). the matrix storage, packed-style, okayurrr 💜
• AFAC — AFAC is COMPLEX*16 array, dimension (NMAX*(NMAX+1)/2). factored matrix energy, same dimension, no notes ✨
• AINV — AINV is COMPLEX*16 array, dimension (NMAX*(NMAX+1)/2). inverse matrix storage, also same dimension, she’s consistent 💅
• B — B is COMPLEX*16 array, dimension (NMAX*NRHS). right-hand-side storage, as one does 🎀
• X — X is COMPLEX*16 array, dimension (NMAX*NRHS). solution storage, main character array honestly 👑
• XACT — XACT is COMPLEX*16 array, dimension (NMAX*NRHS). exact-solution storage, the reference bestie 🫶
• WORK — WORK is COMPLEX*16 array, dimension (NMAX*max(2,NRHS)). work array, doing the behind-the-scenes labor 🌸
• RWORK — RWORK is DOUBLE PRECISION array, dimension (NMAX+2*NRHS). real work array, double precision, very serious 🧚
• IWORK — IWORK is INTEGER array, dimension (NMAX). integer work array, keeping it whole-number 🍓
• NOUT — NOUT is INTEGER. the unit number for output. that’s where the results get printed, iykyk 🖨️
