💖 TESTING/LIN/cdrvhex.f(3) 💖

Okay bestie, welcome to the Library Functions Manual page for TESTING/LIN/cdrvhex.f — yes, the header said the title twice, and honestly? Main character energy. We're talking about CDRVHEX and the cdrvhe subroutine, and I'm gonna walk you through every single parameter because we do not gatekeep here. ✨

✨ SYNOPSIS ✨

🎀 Functions/Subroutines

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

🦋 Function/Subroutine Documentation 🦋

Here's the full signature, exactly as the source flexes it:

       subroutine cdrvhe (logical, dimension( * ) dotype, integer nn, integer,
           dimension( * ) nval, integer nrhs, real thresh, logical tsterr, integer
           nmax, complex, dimension( * ) a, complex, dimension( * ) afac, complex,
           dimension( * ) ainv, complex, dimension( * ) b, complex, dimension( * )
           x, complex, dimension( * ) xact, complex, dimension( * ) work, real,
           dimension( * ) rwork, integer, dimension( * ) iwork, integer nout)
           CDRVHEX

🔥 Purpose

CDRVHE tests the driver routines CHESV, -SVX, and -SVXX. 🔥

Heads up, bestie: this file is used only when the XBLAS are available, otherwise cdrvhe.f defines this subroutine. Important lore, no cap. 💅

🌸 Parameters

  • DOTYPE — is a LOGICAL array, dimension (NTYPES). The matrix types to use 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. 🎀
  • NN — is INTEGER. The number of values of N contained in the vector NVAL. ✨
  • NVAL — is INTEGER array, dimension (NN). The values of the matrix dimension N. 🦋
  • NRHS — is INTEGER. The number of right hand side vectors to be generated for each linear system. 💅
  • 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 — is LOGICAL. Flag that indicates whether error exits are to be tested. 👑
  • NMAX — is INTEGER. The maximum value permitted for N, used in dimensioning the work arrays. 🌈
  • A — is COMPLEX array, dimension (NMAX*NMAX). 🍓
  • AFAC — is COMPLEX array, dimension (NMAX*NMAX). 🍓
  • AINV — is COMPLEX array, dimension (NMAX*NMAX). 🍓
  • B — is COMPLEX array, dimension (NMAX*NRHS). 💖
  • X — is COMPLEX array, dimension (NMAX*NRHS). 💖
  • XACT — is COMPLEX array, dimension (NMAX*NRHS). 💖
  • WORK — is COMPLEX array, dimension (NMAX*max(2,NRHS)). 🧚
  • RWORK — is REAL array, dimension (2*NMAX+2*NRHS). 🌸
  • IWORK — is INTEGER array, dimension (NMAX). 🎀
  • NOUT — is INTEGER. The unit number for output. 💜

Okay that's the whole tea, bestie. Signing off with LAPACK, Version 3.12.0, and TESTING/LIN/cdrvhex.f(3) — the footer's source/version/page tag (no extra date shown, just the vibe). Slay. 🌈💖👑
