💖 NAME 💖

TESTING/EIG/zerred.f

✨ SYNOPSIS ✨

Functions/Subroutines

• subroutine zerred (path, nunit) — ZERRED

🎀 Function/Subroutine Documentation 🎀

subroutine zerred (character*3 path, integer nunit)

ZERRED

Purpose:

Okay so listen: ZERRED tests the error exits for the eigenvalue driver routines for DOUBLE COMPLEX PRECISION matrices. It’s giving very much “quality control but make it complex,” and we love that for us. 💅

Here’s the driver lineup, exact names and all:

PATH  driver   description
----  ------   -----------
ZEV   ZGEEV    find eigenvalues/eigenvectors for nonsymmetric A
ZES   ZGEES    find eigenvalues/Schur form for nonsymmetric A
ZVX   ZGEEVX   ZGEEV + balancing and condition estimation
ZSX   ZGEESX   ZGEES + balancing and condition estimation
ZBD   ZGESVD   compute SVD of an M-by-N matrix A
      ZGESDD   compute SVD of an M-by-N matrix A(by divide and
               conquer)
      ZGEJSV   compute SVD of an M-by-N matrix A where M >= N
      ZGESVDX  compute SVD of an M-by-N matrix A(by bisection
               and inverse iteration)
      ZGESVDQ  compute SVD of an M-by-N matrix A(with a
               QR-Preconditioned )

Parameters

• PATH — CHARACTER*3. The LAPACK path name for the routines to be tested. That’s the path, periodt.
• NUNIT — INTEGER. The unit number for output. Output unit tea, no cap.

Sign-off tea: source is LAPACK, version is Version 3.12.0, and the page tag is TESTING/EIG/zerred.f(3). The footer doesn’t show a separate date, so I’m not inventing one — periodt. 🫶💖
