DGET33(3)

💅 NAME

Bestie, welcome to dget33(3) — this page is from the Library Functions Manual, and the file it lives in is /home/abuild/rpmbuild/BUILD/lapack-static-3.12.0-build/lapack-3.12.0/TESTING/EIG/dget33.f.

✨ SYNOPSIS

🧚 Functions/Subroutines

• subroutine DGET33 (rmax, lmax, ninfo, knt) — DGET33

🌸 Function/Subroutine Documentation

🎀 subroutine DGET33 (double precision rmax, integer lmax, integer ninfo, integer knt)

DGET33

🦋 Purpose

Okay so DGET33 is out here testing DLANV2, the routine that puts 2 by 2 blocks into standard form. In other words, it computes a two by two rotation [[C,S] [-S,C]] where in

[ C S ][T(1,1) T(1,2)][ C -S ] = [ T11 T12 ]
[-S C ][T(2,1) T(2,2)][ S  C ]   [ T21 T22 ]

either

1. T21=0 (real eigenvalues), or
2. T11=T22 and T21*T12<0 (complex conjugate eigenvalues).

We also verify that the residual is small. No cap, that's the whole purpose. 🫶

🍓 Parameters

• RMAX — RMAX is DOUBLE PRECISION. Value of the largest test ratio.
• LMAX — LMAX is INTEGER. Example number where largest test ratio achieved.
• NINFO — NINFO is INTEGER. Number of examples returned with INFO .NE. 0.
• KNT — KNT is INTEGER. Total number of examples tested.
