xmin=0.8
xmax=4
n=20
x=xmin+rand(1,n)*(xmax-xmin)

xmin=0.8;
xmax=4;
n = 1e6; % Generating a few more numbers than the original n=20;
x=xmin+rand(1,n)*(xmax-xmin);
histogram(x, 0.8:0.1:4.1)
Looks reasonably uniform to me.

If you want it EXACTLY perfectly uniform (which is doubtful), then you should use linspace() instead of rand().

Did you look in the help? You will see the first example does what you want:
Example 1
Generate values from the uniform distribution on the interval [a, b]:
r = a + (b-a).*rand(100,1);

Hallo, I have seen a tutorial about "Generating Random Number in Specific Range" at https://www.youtube.com/watch?v=MyH3-ONYL_k and it works. Hope it will help you.
