ZDRVPT(3)

💅 NAME

ok so bestie, this is the page for /home/abuild/rpmbuild/BUILD/lapack-static-3.12.0-build/lapack-3.12.0/TESTING/LIN/zdrvpt.f — yes literally that whole entire path, she's a whole journey 🛣️ — and it lives in the Library Functions Manual (that's the manual name, in case you were wondering 🎀).

✨ SYNOPSIS

Functions/Subroutines

• subroutine ZDRVPT (dotype, nn, nval, nrhs, thresh, tsterr, a, d, e, b, x, xact, work, rwork, nout) — ZDRVPT, that's her 💅

🦋 Function/Subroutine Documentation

subroutine ZDRVPT (logical, dimension( * ) dotype, integer nn, integer,
    dimension( * ) nval, integer nrhs, double precision thresh, logical
    tsterr, complex*16, dimension( * ) a, double precision, dimension( * )
    d, complex*16, dimension( * ) e, complex*16, dimension( * ) b,

ZDRVPT — that's the name, say it with me 🗣️

🌸 Purpose:

ZDRVPT tests ZPTSV and -SVX.

like, that's the whole vibe check, no cap 💀

👑 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 a lil yes/no list of which matrix types we're inviting to the party 🎉 (and the ones set to .FALSE. did NOT get an invite, sorry babes 🙈)

• NN

NN is INTEGER 🧮 The number of values of N contained in the vector NVAL.

• NVAL

NVAL is INTEGER array, dimension (NN) 🍓 The values of the matrix dimension N. these are the actual numbers we're testing, bestie, the dimension menu fr fr

• NRHS

NRHS is INTEGER The number of right hand side vectors to be generated for each linear system. yup, that many RHS vectors per system, no more no less 💖

• 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. like okay gatekeeper, we SEE you — if you wanna see literally everything, set that bad boy to 0 and slay 🌈

• TSTERR

TSTERR is LOGICAL Flag that indicates whether error exits are to be tested. 🙈 little on/off switch for the error-path testing, iykyk

• A

A is COMPLEX*16 array, dimension (NMAX*2) 💜

• D

D is DOUBLE PRECISION array, dimension (NMAX*2) 🎀

• E

E is COMPLEX*16 array, dimension (NMAX*2) ⭐

• 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(3,NRHS)) 🧚 — note the max, she's picking the bigger one, main character energy for real

• RWORK

RWORK is DOUBLE PRECISION array, dimension (NMAX+2*NRHS) 🌸 — real-valued workspace, living her double precision life

• NOUT

NOUT is INTEGER The unit number for output. 📝 that's where all the receipts get printed, bestie

okay that's the whole page bestie, you're officially fluent in ZDRVPT now, no cap 🧚

catch you later — this was LAPACK, Version 3.12.0, and the date on this whole thing is literally the path /home/abui...IN/zdrvpt.f(3) (iconic of it tbh) 💖✨🎀
