I'm running the same octave script with the same inputs on different platforms (version 3.8.2 on all of them), but still obtain different results, let's call them A and B: Mac OS X and octave-online.net
yield A, while two different Linux systems yield B. The 'qp'-command seems to be causing this problem. Are there any options that could be responsible, e.g. floating point precision? Other ideas how to fix this problem more than welcome of course.
