TESTING/LIN/ddrvsy_rk.f(3)

NAME 🦋

okay bestie, this is the Library Functions Manual page for TESTING/LIN/ddrvsy_rk.f, and it's giving LAPACK test-driver main character energy. No cap.

SYNOPSIS ✨

Functions/Subroutines 🧚

Here's the subroutine vibe, literally:

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

Function/Subroutine Documentation 💅

The full declaration is this exact thing:

   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

Purpose 🔥

DDRVSY_RK tests the driver routines DSYSV_RK. That's the whole purpose, periodt.

Parameters 👑

• DOTYPE — DOTYPE is LOGICAL array, dimension (NTYPES). It's the matrix-type menu: 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. 🎀
• 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 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. 🔥
• 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 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)). 💅
• 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. 💀
