The most problems are related to EEGLab, sure. Because some of the
Octave-developers deny to be more compatible with Matlab I am not able
to decide what is a real problem by Octave or a compatibility issue.
Only if the result of specific mathematical, isolated operations will
be wrong I had a chance to commit a bugreport, right?

Matlab interpretes the m-files and checks them only in interpreting
state. Octave checks the m-files first, checks the called functions
within and then it will start  the  interpretation-process.  The
problem  is that Matlab programmers only see "the code works", but the
dark corner of their code will not be enlighted because not checked.

Because most developers are only familiar with Matlab-Syntax. They
also work on universities and are mostly not affected with license
fees so there is not enough pressure to switch over to Octave. The
migration of EEGLab from Matlab to Octave is a long term process and a
lot more of compatibility will make things easier.

It seems the easiest way to me, is not it?

But I am very happy if any(!) GUI-functionality will be added soon. So
we are able to build wrappers to use GUI with Octave, too.

This will be corrected soon. I will forward your hint to the official
developer-team.
