Date: Thu, 22 Jan 2009 02:04:47 -0700 From: Vasile Sima To: "lapack@cs.utk.edu" Cc: Pascal Gahinet , Peter Benner Subject: [Lapack] Bug in DHGEQZ / SHGEQZ Hello, [...] I would like to draw your attention to a bug in the file dhgeqz.f (and also in shgeqz.f) included in the archive lapack.tgz, updated on November 18, 2008 on the site http://www.netlib.org/lapack/. Namely, the argument LDH in line 780 must be replaced by LDT. The bug is minor, but can lead to bad results if LDH differs from LDT. [...] Sincerely yours, Vasile Sima
