ZCHKGK(3)

hey bestie 💖 welcome to ZCHKGK(3) from the Library Functions Manual! this page is a LAPACK testing-routine moment, and it's lowkey here to check ZGGBAK — no cap ✨

💖 NAME 💖

the name is literally this file path, and yes it's long enough to need a snack break 🍓:

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

✨ SYNOPSIS ✨

under Functions/Subroutines it's giving:

   Functions/Subroutines
       subroutine ZCHKGK (nin, nout)
           ZCHKGK

🎀 Function/Subroutine Documentation 🎀

okay so the function signature tea ☕:

   subroutine ZCHKGK (integer nin, integer nout)
       ZCHKGK

🦋 Purpose 🦋

the purpose block, verbatim because we keep the facts pristine 🫶:

           !>
           !> ZCHKGK tests ZGGBAK, a routine for backward balancing  of
           !> a matrix pair (A, B).
           !>

translation: it tests ZGGBAK, the routine for backward balancing of a matrix pair (A, B) 💅

🍓 Parameters 🍓

two params, both logical unit numbers, both > 0 — periodt:

NIN

           !>          NIN is INTEGER
           !>          The logical unit number for input.  NIN > 0.
           !>

NOUT

           !>          NOUT is INTEGER
           !>          The logical unit number for output.  NOUT > 0.
           !>
