TESTING/LIN/zdrvpp.f(3)

💅 TESTING/LIN/zdrvpp.f — Library Functions Manual, but make it cute

okay so bestie, welcome to zdrvpp.f — it lives in TESTING/LIN and it's a whole mood. it's the manual entry for a subroutine, and honestly it's giving "quietly doing the most important job in the room." 🎀

---

✨ NAME ✨

TESTING/LIN/zdrvpp.f — the file. that's it. that's the name. iconic behavior, no notes. 👑

🦋 SYNOPSIS 🦋

Functions/Subroutines

• subroutine zdrvpp (dotype, nn, nval, nrhs, thresh, tsterr, nmax, a, afac, asav, b, bsav, x, xact, s, work, rwork, nout) — the whole squad, assembled. ZDRVPP in the building. 🔥

🌸 Function/Subroutine Documentation 🌸

subroutine zdrvpp (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( * ) asav, complex*16, dimension( * ) b, complex*16, dimension( * ) bsav, complex*16, dimension( * ) x, complex*16, dimension( * ) xact, double precision, dimension( * ) s, complex*16, dimension( * ) work, double precision, dimension( * ) rwork, integer nout)

ZDRVPP

🧚 Purpose:

ZDRVPP tests the driver routines ZPPSV and -SVX.

literally its whole personality. it tests ZPPSV and -SVX. periodt. ✨

💖 Parameters 💖

grab a snack, bestie, because there are a LOT of them and we're doing all of them. no skipping. 🍓

• DOTYPE — DOTYPE is LOGICAL array, dimension (NTYPES) the matrix types to be used for testing. matrices of type j (for 1 <= j <= NTYPES) get tested if DOTYPE(j) = .TRUE.; if DOTYPE(j) = .FALSE., then type j is not used. so it's literally the guest list and you're the bouncer. 🚪
• NN — NN is INTEGER the number of values of N contained in the vector NVAL. it's giving "how many vibes are we checking."
• NVAL — NVAL is INTEGER array, dimension (NN) the values of the matrix dimension N. the actual sizes. the main characters. 👑
• NRHS — NRHS is INTEGER the number of right hand side vectors to be generated for each linear system. yes bestie, right-hand sides. plural. we're not doing one and calling it a day. 💅
• 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. so like. set it to 0 if you're nosy. 🙈
• TSTERR — TSTERR is LOGICAL flag that indicates whether error exits are to be tested. do we test the sad paths? this flag decides. 😭
• NMAX — NMAX is INTEGER the maximum value permitted for N, used in dimensioning the work arrays. the ceiling. the limit. the "don't get too comfy."
• A — A is COMPLEX*16 array, dimension (NMAX*(NMAX+1)/2)
• AFAC — AFAC is COMPLEX*16 array, dimension (NMAX*(NMAX+1)/2)
• ASAV — ASAV is COMPLEX*16 array, dimension (NMAX*(NMAX+1)/2)
• B — B is COMPLEX*16 array, dimension (NMAX*NRHS)
• BSAV — BSAV 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)
• S — S is DOUBLE PRECISION array, dimension (NMAX)
• WORK — WORK is COMPLEX*16 array, dimension (NMAX*max(3,NRHS)) — note the max(3,NRHS) bestie, it's always at least 3, that's the floor. 🫶
• RWORK — RWORK is DOUBLE PRECISION array, dimension (NMAX+2*NRHS)
• NOUT — NOUT is INTEGER the unit number for output. where the receipts go. 🧾

fr fr bestie, if you're calling this yourself: THRESH = 0 means you see everything, and DOTYPE is a logical array of dimension (NTYPES) so please index it correctly, i'm begging. 🙏

🌸 mwah, that's the whole page 🌸

LAPACK — Version 3.12.0, brought to you from TESTING/LIN/zdrvpp.f(3). go forth and test those driver routines, you absolute icon. 💜🦋💅
