Details:

It is necessary that rand will begin with the same number every time octave is
opened, since the user has to be able to repeat his run with the same result
every time (this is specifically critical for monte carlo simulations). this
is the default in matlab, and can only be achieved by seeding the algo in
octave. for example:


disp(rand(1,10))


should return the same sequence every time octave is opened.
