Generate values from the uniform distribution on the interval [a, b]:
r = a + (b-a).*rand(100,1);
or if you'd want the numbers to be integers,
Use the randi function, instead of rand, to generate integer values from the uniform distribution on the set 1:100:
r = randi(100,1,5);
Although you must note that these numbers are pseudorandom, in that no computer system can in reality generate purely random numbers!
