I want to draw 500 samples from the 20*1 matrix (20 pairs of observations).
In this case, what codes do I have to use?

One way is
% Pretend input data
M = rand(20,1);
idx = randi(20,500,1);
samples = M(idx);

If you have the Statistics and Machine Learning Toolbox, you can do
% Pretend input data
M = rand(20,1);
samples = randsample(M,500,true);
