% generate our random variables: 
N_SAMPS=1e2; 
%x = normrnd(0,sqrt(2),1,N_SAMPS); 
%y = normrnd(0,sqrt(1),1,N_SAMPS); 
x = normrnd(5,sqrt(1),1,N_SAMPS); 
y = normrnd(0,sqrt(1),1,N_SAMPS); 

% get the order statistics: 
xs = sort(x); 
ys = sort(y); 

% construct the q-q plot: 
figure; plot( xs, ys, 'x' ); grid on;
