ZGET36(3)

📦 version 3.12.0, in opensuse-leap 16.0

💖 NAME 💖

/home/abuild/rpmbuild/BUILD/lapack-static-3.12.0-build/lapack-3.12.0/TESTING/EIG/zget36.f

Okay bestie, this is the zget36.f(3) page from the Library Functions Manual — manual name folded in right here, no copy-pasted header line needed 💅.

✨ SYNOPSIS ✨

🌈 Functions/Subroutines 🌈

subroutine ZGET36 (rmax, lmax, ninfo, knt, nin)
    ZGET36

🦋 Function/Subroutine Documentation 🦋

subroutine ZGET36 (double precision rmax, integer lmax, integer ninfo,
    integer knt, integer nin)
    ZGET36

🎀 Purpose 🎀

So ZGET36 tests ZTREXC — that's the routine for reordering diagonal entries of a matrix in complex Schur form. The page also says, literally, that ZLAEXC computes a unitary matrix Q such that:

Q' * T1 * Q  = T2

...and where one of the diagonal blocks of T1 — the one at row IFST — has been moved to position ILST ✨.

The test code verifies that the residual Q'*T1*Q-T2 is small, that T2 is in Schur form, and that the final position of the IFST block is ILST. Periodt 💅.

The test matrices are read from a file with logical unit number NIN. Slay.

🧸 Parameters 🧸

  • RMAX — DOUBLE PRECISION; value of the largest test ratio.
  • LMAX — INTEGER; example number where largest test ratio achieved.
  • NINFO — INTEGER; number of examples where INFO is nonzero.
  • KNT — INTEGER; total number of examples tested.
  • NIN — INTEGER; input logical unit number.
