ZGET37(3)

hey bestie! welcome to the ZGET37(3) page from the Library Functions Manual — it’s giving “subroutine test energy” and honestly it’s kinda iconic. 💅✨

🎀 NAME 🎀

/home/abuild/rpmbuild/BUILD/lapack-static-3.12.0-build/lapack-3.12.0/TESTING/EIG/zget37.f

✨ SYNOPSIS ✨

🌸 Functions/Subroutines 🌸

• subroutine ZGET37 (rmax, lmax, ninfo, knt, nin) — ZGET37

🦋 Function/Subroutine Documentation 🦋

Here’s the full signature, bestie — copy it exactly, no cap:

   subroutine ZGET37 (double precision, dimension( 3 ) rmax, integer,
       dimension( 3 ) lmax, integer, dimension( 3 ) ninfo, integer knt, integer
       nin)

ZGET37

🌈 Purpose

okay so lowkey what this does: ZGET37 tests ZTRSNA, a routine for estimating condition numbers of eigenvalues and/or right eigenvectors of a matrix. 💖

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

💜 Parameters

• RMAX — RMAX is DOUBLE PRECISION array, dimension (3). Value of the largest test ratio.
  • RMAX(1) = largest ratio comparing different calls to ZTRSNA
  • RMAX(2) = largest error in reciprocal condition numbers taking their conditioning into account
  • RMAX(3) = largest error in reciprocal condition numbers not taking their conditioning into account (may be larger than RMAX(2))
• LMAX — LMAX is INTEGER array, dimension (3). LMAX(i) is example number where largest test ratio RMAX(i) is achieved. Also:
  • If ZGEHRD returns INFO nonzero on example i, LMAX(1)=i
  • If ZHSEQR returns INFO nonzero on example i, LMAX(2)=i
  • If ZTRSNA returns INFO nonzero on example i, LMAX(3)=i
• NINFO — NINFO is INTEGER array, dimension (3).
  • NINFO(1) = No. of times ZGEHRD returned INFO nonzero
  • NINFO(2) = No. of times ZHSEQR returned INFO nonzero
  • NINFO(3) = No. of times ZTRSNA returned INFO nonzero
• KNT — KNT is INTEGER. Total number of examples tested.
• NIN — NIN is INTEGER. Input logical unit number.
