CGET37(3)

Hey bestie 💖 welcome to CGET37(3), from the Library Functions Manual — yep, the header vibe is /home/abui...IG/cget37.f(3), and the full file path is chillin’ in NAME below. This page is giving serious LAPACK test-routine energy, so let’s get into it.

💖 NAME 💖

Okay so the name is literally this file path, no cap:

/home/abuild/rpmbuild/BUILD/lapack-static-3.12.0-build/lapack-3.12.0/TESTING/EIG/cget37.f

---

✨ SYNOPSIS ✨

Functions/Subroutines — yes bestie, it’s subroutine hours:

subroutine CGET37 (rmax, lmax, ninfo, knt, nin)
    CGET37

🫶 Function/Subroutine Documentation 🫶

💅 The subroutine signature 💅

subroutine CGET37 (real, dimension( 3 ) rmax, integer, dimension( 3 ) lmax,
    integer, dimension( 3 ) ninfo, integer knt, integer nin)
    CGET37

🎀 Purpose 🎀

Okay so the whole point: CGET37 tests CTRSNA, 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. Obsessed with a routine that actually reads its test matrices from a file, honestly. 💅

Bestie, don’t miss that logical unit number NIN — it’s the input file hookup.

🌸 Parameters 🌸

• RMAX — RMAX is REAL array, dimension (3). It’s the value of the largest test ratio.
  • RMAX(1) = largest ratio comparing different calls to CTRSNA
  • 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 CTRSNA 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 CTRSNA returned INFO nonzero
• KNT — KNT is INTEGER. Total number of examples tested. Iconic counting behavior. 🔥
• NIN — NIN is INTEGER. Input logical unit number. 🎀
