rand( ) is a random number generator ... it is supposed to give a different result.
doc rand
If you want to start over with the same stream of numbers you will need to re-seed it.

All the random number functions, rand, randn, randi, and randperm, draw values from a shared random number generator. Every time you start MATLAB, the generator resets itself to the same state.
The rand function draw values from a RandStream.
