💖 DGET37(3) — Library Functions Manual 💖

okay so bestie, welcome to DGET37(3) from the Library Functions Manual — header path vibe: /home/abui...IG/dget37.f(3). This is the page for the DGET37 test routine. 🫶

🎀 NAME 🎀

/home/abuild/rpmbuild/BUILD/lapack-static-3.12.0-build/lapack-3.12.0/TESTING/EIG/dget37.f

That’s the source file, fr fr. 💅

✨ SYNOPSIS ✨

🧚 Functions/Subroutines 🧚

       subroutine DGET37 (rmax, lmax, ninfo, knt, nin)
           DGET37

🦋 Function/Subroutine Documentation 🦋

       subroutine DGET37 (double precision, dimension( 3 ) rmax, integer,
       dimension( 3 ) lmax, integer, dimension( 3 ) ninfo, integer knt, integer
       nin)
           DGET37

🌸 Purpose 🌸

DGET37 tests DTRSNA, 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. no cap, that’s the whole vibe check. 👑

💜 Parameters 💜

• RMAX — RMAX is DOUBLE PRECISION array, dimension (3). Value of the largest test ratio. So:
  • RMAX(1) = largest ratio comparing different calls to DTRSNA
  • 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 DGEHRD returns INFO nonzero on example i, LMAX(1)=i
  • If DHSEQR returns INFO nonzero on example i, LMAX(2)=i
  • If DTRSNA returns INFO nonzero on example i, LMAX(3)=i
• NINFO — NINFO is INTEGER array, dimension (3). The counts are giving:
  • NINFO(1) = No. of times DGEHRD returned INFO nonzero
  • NINFO(2) = No. of times DHSEQR returned INFO nonzero
  • NINFO(3) = No. of times DTRSNA returned INFO nonzero
• KNT — KNT is INTEGER. Total number of examples tested. 💯
• NIN — NIN is INTEGER. Input logical unit number. 🎀
