I think this has changed.  In R13, function handles were an array
type, so indexing them picked an element from the array.  In R14, they
made them a scalar type only, so indexing them performs a function
call.  So in the above, you are selecting the first element of the
function handle array stored in f.  Try

  ff (@sin, 2)

and see if you don't get a different result (range error on the
index).

With the new behavior, I would expect Matlab to be compatible with the
current Octave behavior and call the sin function through the function
handle with the argument 1.
