% Dimension of A and b
n = 2;

% Generate all vectors x of dimension d with coordinates between -range and +range
step  = 1;
range = 20; 
interval = -range:step:range; % the window of x to be observed regarding the set 'C'

% Generate all combinations in the defined range
x = combn(interval, n); x = x';
