I'm confused. Are you asking why Octave handles "e" as it does "pi" or  
why Matlab does not?

Regarding a better way, I'd create a function in Matlab and place it  
in the path.

----------- save as "e.m" -----------
function a = e ()
  a = exp(1);
end
------------------------------------------

That way "e" will be available to all your scripts and functions.
