💅 NAME

/home/abuild/rpmbuild/BUILD/lapack-static-3.12.0-build/lapack-3.12.0/TESTING/LIN/ddrvsy_rk.f

okay so bestie, this is a page from the Library Functions Manual for that exact file right there — and it's a Fortran test-driver routine living its best life inside LAPACK's TESTING/LIN folder 🎀. It's not glamorous, but it's essential, iykyk.

✨ SYNOPSIS ✨

Functions/Subroutines

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

DDRVSY_RK — that's the whole vibe, that's the name, periodt 💅

🦋 Function/Subroutine Documentation 🦋

Here's the full signature with all its types and dimensions, no cap, nothing dropped:

subroutine DDRVSY_RK (logical, dimension( * ) dotype, integer nn, integer,
    dimension( * ) nval, integer nrhs, double precision thresh, logical
    tsterr, integer nmax, double precision, dimension( * ) a, double
    precision, dimension( * ) afac, double precision, dimension( * ) e,
    double precision, dimension( * ) ainv, double precision, dimension( * )
    b, double precision, dimension( * ) x, double precision, dimension( * )
    xact, double precision, dimension( * ) work, double precision,
    dimension( * ) rwork, integer, dimension( * ) iwork, integer nout)

DDRVSY_RK — yes, again, she's iconic and she knows it 👑

🎀 Purpose 🎀

DDRVSY_RK tests the driver routines DSYSV_RK.

that's it. that's the whole purpose. short, sweet, main character energy fr fr 💖

🌸 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. literally a little yes/no checklist for which matrix types get to audition 💅
• NN — NN is INTEGER. The number of values of N contained in the vector NVAL. so basically how many sizes we're gonna test, ngl.
• NVAL — NVAL is INTEGER array, dimension (NN). The values of the matrix dimension N. these are the actual sizes, the lewks, the fits 🦋
• NRHS — NRHS is INTEGER. The number of right hand side vectors to be generated for each linear system. yup, that many right-hand sides 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 nosy and want everything, you know what to do 💀
• TSTERR — TSTERR is LOGICAL. Flag that indicates whether error exits are to be tested. do we poke the error paths? this flag says yes/no 🙈
• NMAX — NMAX is INTEGER. The maximum value permitted for N, used in dimensioning the work arrays. the ceiling, the limit, the "don't go past this" 🎀
• A — A is DOUBLE PRECISION array, dimension (NMAX*NMAX).
• AFAC — AFAC is DOUBLE PRECISION array, dimension (NMAX*NMAX).
• E — E is DOUBLE PRECISION array, dimension (NMAX).
• AINV — AINV is DOUBLE PRECISION array, dimension (NMAX*NMAX).
• B — B is DOUBLE PRECISION array, dimension (NMAX*NRHS).
• X — X is DOUBLE PRECISION array, dimension (NMAX*NRHS).
• XACT — XACT is DOUBLE PRECISION array, dimension (NMAX*NRHS).
• WORK — WORK is DOUBLE PRECISION array, dimension (NMAX*max(2,NRHS)). note the max(2,NRHS) bestie, she's got range 🔥
• RWORK — RWORK is DOUBLE PRECISION array, dimension (NMAX+2*NRHS).
• IWORK — IWORK is INTEGER array, dimension (2*NMAX).
• NOUT — NOUT is INTEGER. The unit number for output. where the tea gets spilled, output-wise ☕
