This might be what you need

 q=rand(3,3);    % generate 3x3 random matrix
 a=0.1; b=0.3; c=0.5;d=0.9;  %values of a b c and d

 x=q(q>a&q<b)   % to find value greater than a and less than b in matrix q
 y=q(q>c&q<d)   % to find value greater than c and less than d in matrix q

Thanks, but more specifically I want to have some part of q that has (x=>a&x<b &y=>c&y<d). I mean each array in q has an x and y, so I want to select q according to (x=>a&x<b &y=>c&y<d) and put them in a new matrix. Would you please help me?
