🌸 TESTING/LIN/zdrvsy_rk.f(3) — Library Functions Manual

Okay so this page is giving “Doxygen-generated LAPACK testing lore,” and we’re gonna read it together without missing a single detail. 💅

🌸 NAME

The main character is TESTING/LIN/zdrvsy_rk.f — that’s the literal file/name, bestie. No edits, no nickname. 🎀

✨ SYNOPSIS

🧚 Functions/Subroutines

This page is serving one subroutine, and her name is ZDRVSY_RK. The call shape is exactly:

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

And yes, the icon herself gets her own line: ZDRVSY_RK. 🦋

🦋 Function/Subroutine Documentation

Here’s the full signature with all the types, dimensions, and lowercase Fortran energy — copied exactly, no cap:

   subroutine zdrvsy_rk (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( * ) e, complex*16,
       dimension( * ) ainv, complex*16, dimension( * ) b, complex*16,
       dimension( * ) x, complex*16, dimension( * ) xact, complex*16,
       dimension( * ) work, double precision, dimension( * ) rwork, integer,
       dimension( * ) iwork, integer nout)

ZDRVSY_RK — that’s her. ✨

🎯 Purpose

ZDRVSY_RK tests the driver routines ZSYSV_RK.

Literally that’s the 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. So it’s the “which matrix types are invited to the test party” list.
• 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. All the N values, lined up cute.
• 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. Set it to 0 if you want the whole test-ratio timeline, no filter.
• 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. Size matters, but only for the work arrays.
• A — A is COMPLEX*16 array, dimension (NMAX*NMAX). 🦋
• AFAC — AFAC is COMPLEX*16 array, dimension (NMAX*NMAX). 💅
• E — E is COMPLEX*16 array, dimension (NMAX). ✨
• AINV — AINV is COMPLEX*16 array, dimension (NMAX*NMAX). 🌸
• B — B 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). 💖
• WORK — WORK is COMPLEX*16 array, dimension (NMAX*max(2,NRHS)). Note the exact max(2,NRHS) — she’s built different.
• RWORK — RWORK is DOUBLE PRECISION array, dimension (NMAX+2*NRHS). 🌈
• IWORK — IWORK is INTEGER array, dimension (NMAX). ⭐
• NOUT — NOUT is INTEGER. The unit number for output. 🍓
