💖 TESTING/EIG/sget37.f 💖

okay bestie, welcome to the Library Functions Manual page for TESTING/EIG/sget37.f ✨ it’s giving tiny test-routine main character energy, and honestly? obsessed 🫶

🎀 NAME 🎀

TESTING/EIG/sget37.f

🌟 SYNOPSIS 🌟

🦋 Functions/Subroutines 🦋

       subroutine sget37 (rmax, lmax, ninfo, knt, nin)
           SGET37

🔥 Function/Subroutine Documentation 🔥

   subroutine sget37 (real, dimension( 3 ) rmax, integer, dimension( 3 ) lmax,
       integer, dimension( 3 ) ninfo, integer knt, integer nin)
       SGET37

The subroutine’s name tag is literally SGET37 — no cap, that’s the whole label 💅

🌸 Purpose 🌸

SGET37 tests STRSNA, 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 a REAL array, dimension (3). It holds the value of the largest test ratio. 💖
    • RMAX(1) = largest ratio comparing different calls to STRSNA.
    • 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 an INTEGER array, dimension (3). LMAX(i) is the example number where the largest test ratio RMAX(i) is achieved. Also: ✨
    • If SGEHRD returns INFO nonzero on example i, LMAX(1)=i.
    • If SHSEQR returns INFO nonzero on example i, LMAX(2)=i.
    • If STRSNA returns INFO nonzero on example i, LMAX(3)=i.
  • NINFO — NINFO is an INTEGER array, dimension (3). It counts the chaos: 😭
    • NINFO(1) = No. of times SGEHRD returned INFO nonzero.
    • NINFO(2) = No. of times SHSEQR returned INFO nonzero.
    • NINFO(3) = No. of times STRSNA returned INFO nonzero.
  • KNT — KNT is an INTEGER. It’s the total number of examples tested. 🔥
  • NIN — NIN is an INTEGER. It’s the input logical unit number. 🎀
