Ran in:
Are you sure that you read the help carefully? For a uniformly distributed integer, you may use X = randi([imin,imax]).
randi([5 10], 1, 10)
ans = 1×10
8 9 10 6 7 5 5 9 9 10

I don't know what randr() is, but consider uniform random numbers between [5 5.2];
using rand:
x = 5 + rand([1 10])*(5.2-5)
x = 1×10
5.1181 5.1719 5.0095 5.0468 5.0215 5.0996 5.1696 5.0610 5.0519 5.1974
or using the attached file:
x = randrange([5 5.2],[1 10])
x = 1×10
5.1053 5.0703 5.1516 5.0715 5.1316 5.0781 5.0687 5.1871 5.1823 5.1664
For integers, you can use randi(), as Yazan suggests.
