CGET38(3)

📦 version 3.12.0, in opensuse-leap 16.0

🎀 NAME 🎀

okay so bestie, welcome to the Library Functions Manual page for CGET38. The NAME is literally this path, no extra lore:

/home/abuild/rpmbuild/BUILD/lapack-static-3.12.0-build/lapack-3.12.0/TESTING/EIG/cget38.f

✨ SYNOPSIS ✨

🌈 Functions/Subroutines 🌈

It’s giving one subroutine, main character energy:

subroutine CGET38 (rmax, lmax, ninfo, knt, nin)
    CGET38

🌸 Function/Subroutine Documentation 🌸

🦋 subroutine CGET38 🦋

The exact signature is a whole mood:

subroutine CGET38 (real, dimension( 3 ) rmax, integer, dimension( 3 ) lmax,
    integer, dimension( 3 ) ninfo, integer knt, integer nin)
    CGET38

This is CGET38. 💖

🔥 Purpose 🔥

CGET38 tests CTRSEN, a routine for estimating condition numbers of a cluster of eigenvalues and/or its associated right invariant subspace. ✨

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

🍓 Parameters 🍓

  • RMAX — RMAX is REAL array, dimension (3). It holds values of the largest test ratios. 💅
    • RMAX(1) = largest residuals from CHST01 or comparing different calls to CTRSEN
    • 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 CGEHRD returns INFO nonzero on example i, LMAX(1)=i
    • If CHSEQR returns INFO nonzero on example i, LMAX(2)=i
    • If CTRSEN returns INFO nonzero on example i, LMAX(3)=i
  • NINFO — NINFO is INTEGER array, dimension (3).
    • NINFO(1) = No. of times CGEHRD returned INFO nonzero
    • NINFO(2) = No. of times CHSEQR returned INFO nonzero
    • NINFO(3) = No. of times CTRSEN returned INFO nonzero
  • KNT — KNT is INTEGER. Total number of examples tested. ✅
  • NIN — NIN is INTEGER. Input logical unit number. 📥
