You have to split up the compound condition into two conditions:
(x1 <= x) && (x <= x2)
If these terms are scalars, that will generate a scalar logical value. If they are not scalars, you should read about logical indexing.
Also, if you are just getting started with Matlab, I would highly recommend that you take a couple of hours to go through the free online tutorial: Matlab Onramp

Hello Alexander
You should use the & statement
x=1:10;
%Let's say you want to find the values of x between 3 and 7
x1=3;
x2=7;
x>=3 & x<=7
ans = 1×10 logical array
0 0 1 1 1 1 1 0 0 0
x(x>=3 & x<=7)
ans = 1×5
3 4 5 6 7
