Hi;
This may help you;
round(3*rand(1,N)) where N is the length of your vector.
 

opps!!!!!!!!! i need to do this in matlab simulink, not in code . please help me out.
 

sorry, missed that point.
But if you cannot achieve doing so in Simulink, may be you can try somethink like this (in worst case)
