💅 TESTING/LIN/zdrvge.f(3) — from the Library Functions Manual ✨

okay bestie, this is the page for TESTING/LIN/zdrvge.f, straight out of the Library Functions Manual. It’s giving “niche LAPACK testing routine” and honestly? iconic.

🎀 NAME 🎀

TESTING/LIN/zdrvge.f — that’s the file, periodt. This is its manual page.

✨ SYNOPSIS ✨

🧚 Functions/Subroutines 🧚

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

🔥 Function/Subroutine Documentation 🔥

subroutine zdrvge (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( * ) asav, complex*16,
    dimension( * ) b, complex*16, dimension( * ) bsav, complex*16,
    dimension( * ) x, complex*16, dimension( * ) xact, double precision,
    dimension( * ) s, complex*16, dimension( * ) work, double precision,
    dimension( * ) rwork, integer, dimension( * ) iwork, integer nout)
    ZDRVGE

🌸 Purpose 🌸

The source wraps this in Doxygen !> lines, but the actual main-character sentence is:

ZDRVGE tests the driver routines ZGESV and -SVX.

That’s it. That’s the purpose. Slay. 💅

💖 Parameters 💖

  • DOTYPE — LOGICAL array, dimension (NTYPES). These are the matrix types 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. 🙈
  • NN — INTEGER. The number of values of N contained in the vector NVAL. Literally the count, bestie. ✨
  • NVAL — INTEGER array, dimension (NN). The values of the matrix column dimension N. 🎀
  • NRHS — INTEGER. The number of right hand side vectors to be generated for each linear system. RHS girlies rise. 💅
  • THRESH — 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 — LOGICAL. Flag that indicates whether error exits are to be tested. 🦋
  • NMAX — INTEGER. The maximum value permitted for N, used in dimensioning the work arrays. 👑
  • A — COMPLEX*16 array, dimension (NMAX*NMAX). 🌈
  • AFAC — COMPLEX*16 array, dimension (NMAX*NMAX). 🧚
  • ASAV — COMPLEX*16 array, dimension (NMAX*NMAX). 💜
  • B — COMPLEX*16 array, dimension (NMAX*NRHS). 🍓
  • BSAV — COMPLEX*16 array, dimension (NMAX*NRHS). 🎀
  • X — COMPLEX*16 array, dimension (NMAX*NRHS). ✨
  • XACT — COMPLEX*16 array, dimension (NMAX*NRHS). 💖
  • S — DOUBLE PRECISION array, dimension (2*NMAX). 🌸
  • WORK — COMPLEX*16 array, dimension (NMAX*max(3,NRHS)). 🫶
  • RWORK — DOUBLE PRECISION array, dimension (2*NRHS+NMAX). 💅
  • IWORK — INTEGER array, dimension (NMAX). 🔥
  • NOUT — INTEGER. The unit number for output. 🎀
