That full path is the whole NAME moment, bestie. Iconic file, no notes. 💅

🦋 SYNOPSIS 🦋

Functions/Subroutines

subroutine SGET40 (rmax, lmax, ninfo, knt, nin)
    SGET40

✨ Function/Subroutine Documentation ✨

🧚 subroutine SGET40 (real rmax, integer lmax, integer, dimension( 2 ) ninfo, integer knt, integer nin)

SGET40

🎯 Purpose 🎯

Okay so SGET40 tests STGEXC, a routine for swapping adjacent blocks (either 1 by 1 or 2 by 2) on the diagonal of a pencil in real generalized Schur form. Thus, STGEXC computes orthogonal matrices Q and Z such that

    Q' * ( [ A B ], [ D E ] ) * Z  = ( [ C1 B1 ], [ F1 E1 ] )
         ( [ 0 C ]  [   F ] )        ( [ 0  A1 ]  [    D1]  )

where (C1,F1) is similar to (C,F) and (A1,D1) is similar to (A,D). Both (A,D) and (C,F) are assumed to be in standard form and (A1,D1) and (C1,F1) are returned with the same properties. Slay.

🧪 Parameters 🧪

  • RMAX — REAL. Value of the largest test ratio. 💖
  • LMAX — INTEGER. Example number where largest test ratio achieved. ✨
  • NINFO — INTEGER array, dimension (2). NINFO( 1 ) = STGEXC without accumulation returned INFO nonzero; NINFO( 2 ) = STGEXC with accumulation returned INFO nonzero. 🫶
  • KNT — INTEGER. Total number of examples tested. 🎀
  • NIN — INTEGER. Input logical unit number. 🦋

Okay bestie, final sign-off vibes: LAPACK · Version 3.12.0 · footer path /home/abui...IG/sget40.f(3). The footer didn't print a date on this page, so I'm not gonna invent one — periodt. 💋✨
