I first asked myself a question about 'end' in the above, and decided to
find an answer using 'help end' in 'octave-3.0.5', so here its output:

"
help end

*** end:

 -- Keyword: end
     Mark the end of any `for', `if', `do', `while', or `function'
     block.

     See also: for, if, do, while, function.


Additional help for built-in functions and operators is
available in the on-line version of the manual.  Use the command
`doc <topic>' to search the manual index.

Help and information about Octave is also available on the WWW
at http://www.octave.org and via the address@hidden
mailing list.
".

So to which of "for', `if', `do', `while', or `function'" 'end' here
belongs ?

Thanks,
  Sergei.
