The rand function generates randum numbers between 0 and 1, not including 0 or 1:

rand

ans = 0.2257

rand(1,5)

ans = 1×5

0.6583 0.2099 0.4393 0.8476 0.4583

rand(3)

ans = 3×3

0.2514 0.5840 0.3004 0.1508 0.9781 0.8052 0.5088 0.2080 0.5720

rng(1);%make the output of rand() repeatable
R=min(rand(1e7,1));
[0 R 1]

ans = 1×3

0 0.0000 1.0000

Although sometimes the returned value might be displayed as 0.

R = 3.0078e-07
