Jordi,
Please try to use a descriptive subject line when posting to this list.
Matlab used to be slow in loops, but now has JIT technology. This has
been discussed here many times before:
http://www.octave.org/octave-lists/archive/help-octave.2004/msg00744.html
http://www.octave.org/octave-lists/archive/help-octave.2006/msg00853.html
http://www.octave.org/octave-lists/archive/help-octave.2005/msg02597.html
and we even have this thread about trying to port JIT to octave
http://www.octave.org/octave-lists/archive/help-octave.2004/msg01524.html
I think the overall conclusion is the JIT is very hard to do and octave
project, which relies on volunteers, does not currently have the
manpower to do it. Maybe you can help?

Of all the complaints I have heard about Octave, its slowness is the

So, I'm interested to know, any idea why this is happening? Why would
a simple for loop with no code to execute except running through all
the values of its iterator take orders of magnitude more in Octave
than in Matlab?
Where are these benchmarks?
