This was discussed in the thread starting with:

http://lists.gnu.org/archive/html/help-octave/2009-08/msg00037.html

Summarizing, this behaviour of Octave might have been introduced
without a strong reason, but it has regarded as to be useful.

As an example, the optim package has functions which call user
functions under certain circumstances with an additional informational
input argument, which users probalbly only rarely need. Matlabs
behaviour would require users to always account for this additional
argument in their function interfaces.
