If Ruby and Octave are correct, then <math>M</math> is a normal matrix. If Factor is correct, then <math>M</math> is ''not'' a normal matrix. '''Factor is wrong.''' Factor's [[matrix multiplication]] has a bug: Factor confuses [https://duckduckgo.com/?q=Hermitian+inner+product Hermitian inner product] with [[scalar product]], and calculates ''<span style="text-decoration: overline">A</span> × B'' in place of ''A × B''. --[[User:Kernigh|Kernigh]] 00:30, 17 March 2012 (UTC) |
