If this is not a homework question then you can use randi(): https://www.mathworks.com/help/matlab/ref/randi.html instead of rand()
x = randi([0 3], 1, 1000);
If the set have non conseutive integers then you can use randsamples(): https://www.mathworks.com/help/releases/R2020b/stats/randsample.html 
randsample([0 1 2 3], 1000, true)
