Hi.. I would like to select random values each iteration (some of them will be repeated )how could I do that ?

The output should be something like the following: [5 2 3 1 1 3 4]

clearvars;
clc
y=[1 5 4 3 2];
for i=1:8
new_y=y(randperm(i))
end

In the future please respond with a comment instead of a new question. You essentially asked the same question half an hour ago.

If you only want a single value from your array I would suggest this code:

clearvars;
clc
y=[1 5 4 3 2];
for i=1:8
    new_y=y(randi(end));
    %
    %code that uses the new_y scalar
    %
end
