TESTING/LIN/sdrvpb.f(3)

🎀 NAME 🎀

Straight out of the Library Functions Manual, bestie: this is TESTING/LIN/sdrvpb.f — the page title and manual-name energy, folded right in near the top so you know exactly what you're looking at. It's all about the sdrvpb subroutine, and yes, it's giving very specific LAPACK testing vibes. 💖

🌈 SYNOPSIS 🌈

✨ Functions/Subroutines ✨

• subroutine sdrvpb (dotype, nn, nval, nrhs, thresh, tsterr, nmax, a, afac, asav, b, bsav, x, xact, s, work, rwork, iwork, nout) — SDRVPB

subroutine sdrvpb (dotype, nn, nval, nrhs, thresh, tsterr, nmax, a,
    afac, asav, b, bsav, x, xact, s, work, rwork, iwork, nout)

💖 Function/Subroutine Documentation 💖

Okay so here's the actual subroutine signature, and not me preserving every single argument exactly, periodt:

subroutine sdrvpb (logical, dimension( * ) dotype, integer nn, integer,
    dimension( * ) nval, integer nrhs, real thresh, logical tsterr, integer
    nmax, real, dimension( * ) a, real, dimension( * ) afac, real,
    dimension( * ) asav, real, dimension( * ) b, real, dimension( * ) bsav,
    real, dimension( * ) x, real, dimension( * ) xact, real, dimension( * )
    s, real, dimension( * ) work, real, dimension( * ) rwork, integer,
    dimension( * ) iwork, integer nout)

This bad boi is SDRVPB. 🫶

💫 Purpose 💫

SDRVPB tests the driver routines SPBSV and -SVX. That's the whole purpose, and it's honestly iconic. ✨

🌸 Parameters 🌸

• DOTYPE — DOTYPE is LOGICAL array, dimension (NTYPES). These are 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. No cap. 💅
• 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.
• NRHS — NRHS is INTEGER. The number of right hand side vectors to be generated for each linear system.
• THRESH — THRESH is REAL. 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.
• TSTERR — TSTERR is LOGICAL. Flag that indicates whether error exits are to be tested.
• NMAX — NMAX is INTEGER. The maximum value permitted for N, used in dimensioning the work arrays.
• A — A is REAL array, dimension (NMAX*NMAX).
• AFAC — AFAC is REAL array, dimension (NMAX*NMAX).
• ASAV — ASAV is REAL array, dimension (NMAX*NMAX).
• B — B is REAL array, dimension (NMAX*NRHS).
• BSAV — BSAV is REAL array, dimension (NMAX*NRHS).
• X — X is REAL array, dimension (NMAX*NRHS).
• XACT — XACT is REAL array, dimension (NMAX*NRHS).
• S — S is REAL array, dimension (NMAX).
• WORK — WORK is REAL array, dimension (NMAX*max(3,NRHS)).
• RWORK — RWORK is REAL array, dimension (NMAX+2*NRHS).
• IWORK — IWORK is INTEGER array, dimension (NMAX).
• NOUT — NOUT is INTEGER. The unit number for output.

mwah 💋 this whole page is from LAPACK, Version 3.12.0, and it's the TESTING/LIN/sdrvpb.f(3) page — Doxygen auto-generated it from the source code, and that's the cute little sign-off. 🫶💖
