Installer of octave-3.2.4/mingw32 makes oct2mat autoload if all octave-forge packages are installed. This is known as the oct2mat issue of the current octave for windows package. Please see http://wiki.octave.org/wiki.pl?OctaveForWindows 1. Standalone ports 1.1. Octave 3.2.4 for Windows MinGW32 Additional important topics found after the release: Regards Tatsuro --- Philip Nienhuis wrote: > <I forgot to include the list...> > > > Hi there Ramon, > > sorry for long reply but it's a reply to 2 mails in one :-) > > Ramon Bueno wrote: > > Hello Phillip, > > ... with one "l" please... :-) (Don't worry, just nitty gritty) > > > a) Down below are the additional COM/ActiveX & java tests you requested > > and their results. > > Actually all test results look good.... read on. > > > b) Regarding the script I left running last night: This morning I saw > > these final messages in the Octave window.
