DGET32(3)

📦 version 3.12.0, in opensuse-leap 16.0

Hey bestie 💖 welcome to the Library Functions Manual page for dget32.f(3). This is the full glow-up of the entry for /home/abui...IG/dget32.f(3), and yes, every technical detail is staying. No cap. ✨

🌸 NAME 🌸

The NAME section is literally this exact path:

/home/abuild/rpmbuild/BUILD/lapack-static-3.12.0-build/lapack-3.12.0/TESTING/EIG/dget32.f

That's it. It's giving file-path main character energy. 🎀

✨ SYNOPSIS ✨

Functions/Subroutines

subroutine DGET32 (rmax, lmax, ninfo, knt)

DGET32

Drive-by synopsis: DGET32 takes rmax, lmax, ninfo, knt. Slay. 💅

🦋 Function/Subroutine Documentation 🦋

subroutine DGET32 (double precision rmax, integer lmax, integer ninfo,
    integer knt)

DGET32

Full signature with types: double precision rmax, integer lmax, integer ninfo, integer knt. It's the same DGET32 but now with receipts. ✨

💖 Purpose 💖

Okay so DGET32 tests DLASY2, a routine for solving

op(TL)*X + ISGN*X*op(TR) = SCALE*B

where TL is N1 by N1, TR is N2 by N2, and N1,N2 =1 or 2 only. X and B are N1 by N2, op() is an optional transpose, an ISGN = 1 or -1. SCALE is chosen less than or equal to 1 to avoid overflow in X. (The "an" before ISGN is the manpage's, bestie — I'm not fixing it, I'm just reporting. 💀)

The test condition is that the scaled residual

norm( op(TL)*X + ISGN*X*op(TR) = SCALE*B )
     / ( max( ulp*norm(TL), ulp*norm(TR)) * norm(X), SMLNUM )

should be on the order of 1. Here, ulp is the machine precision. Also, it is verified that SCALE is less than or equal to 1, and that XNORM = infinity-norm(X). Periodt. 👑

🎀 Parameters 🎀

  • RMAX — DOUBLE PRECISION; the value of the largest test ratio. 💖
  • LMAX — INTEGER; example number where largest test ratio achieved. 🌟
  • NINFO — INTEGER; number of examples returned with INFO.NE.0. 🫶
  • KNT — INTEGER; total number of examples tested. 🎯

Cute sign-off time, bestie: the footer's source/version is LAPACK Version 3.12.0, and the path is /home/abui...IG/dget32.f(3). The footer doesn't print a date, so I'm not inventing one — mwah 💋✨
