TESTING/LIN/zdrvpb.f(3)

💅 NAME

okay so bestie, this is the TESTING/LIN/zdrvpb.f(3) page from the Library Functions Manual — the LAPACK page for ZDRVPB, and it's giving test-driver main character energy. 💖

✨ SYNOPSIS

    afac, asav, b, bsav, x, xact, s, work, rwork, nout)

ZDRVPB ✨

🎀 Function/Subroutine Documentation

subroutine zdrvpb (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)

ZDRVPB — yup, that's the subroutine name, and that's the whole vibe. 💅

🌸 Purpose

ZDRVPB tests the driver routines ZPBSV and -SVX. That's the official purpose, and it ate. 🔥

🌈 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. Basically a yes/no list for each matrix type, and we love a clear boundary. ✅
• NN — NN is INTEGER. The number of values of N contained in the vector NVAL. So it's the count of sizes we're about to test, fr fr. 🔢
• NVAL — NVAL is INTEGER array, dimension (NN). The values of the matrix dimension N. The size lineup, periodt. 📏
• NRHS — NRHS is INTEGER. The number of right hand side vectors to be generated for each linear system. RHS besties, assembled per system. 💖
• 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 if you're in your "print everything" era, set it to zero. 🎀
• TSTERR — TSTERR is LOGICAL. Flag that indicates whether error exits are to be tested. Error-exit test mode: on or off, bestie. 🚦
• NMAX — NMAX is INTEGER. The maximum value permitted for N, used in dimensioning the work arrays. Big-N ceiling, iconic. 👑
• A — A is COMPLEX*16 array, dimension (NMAX*NMAX). That's the whole note. 💅
• AFAC — AFAC is COMPLEX*16 array, dimension (NMAX*NMAX). Same energy, different array. ✨
• ASAV — ASAV is COMPLEX*16 array, dimension (NMAX*NMAX). Saved-array behavior, no extra lore. 🎀
• B — B is COMPLEX*16 array, dimension (NMAX*NRHS). The right-hand-side bestie. 💖
• BSAV — BSAV is COMPLEX*16 array, dimension (NMAX*NRHS). Same dimension, saved vibe. 🦋
• X — X is COMPLEX*16 array, dimension (NMAX*NRHS). The solution-ish array, living its truth. 🌸
• XACT — XACT is COMPLEX*16 array, dimension (NMAX*NRHS). Exact-array energy, iykyk. ⭐
• S — S is DOUBLE PRECISION array, dimension (NMAX). Precision bestie, keeping it real. 💜
• WORK — WORK is COMPLEX*16 array, dimension (NMAX*max(3,NRHS)). The work array said "I contain multitudes" and meant it. 🫶
• RWORK — RWORK is DOUBLE PRECISION array, dimension (NMAX+2*NRHS). Real-work array, doing real-work things. 🌈
• NOUT — NOUT is INTEGER. The unit number for output. Where the receipts get printed. 🧾
