In addition octave crashes if we search for the largest eigenvalues ('LM'). I tested it in windows as well in linux. Both with the same behaviour. _______________________________________________________ File Attachments: ------------------------------------------------------- Date: Mon 23 Apr 2018 06:47:04 AM UTC Name: Test_GEVP.m Size: 840B By: stromi <http://savannah.gnu.org/bugs/download.php?file_id=43990> _______________________________________________________ Reply to this item at: <http://savannah.gnu.org/bugs/?53719> _______________________________________________ Message sent via/by Savannah http://savannah.gnu.org/
