How extract the value in certain position for a loop in matlab?

How can I the output in a vector, when I run it I'm getting a single number

ID =[2003;2201;3350;9123;8234;1234]

for i = 1:length(ID)
    y(i) = num2str(ID)
    out(i) = str2num(y(2))
end

I need the third position because that value will give me in another conditional the importance of that element

for i = 1:length(ID)
    if out(i) == 0
        EI(i) = 'Very high';
    elseif out(i) == 1
        EI(i) = 'High';
    elseif out(i) == 2
        EI(i) = 'Medium';
    elseif out(i) == 3
        EI(i)= 'Low';
    end
end

I really appreciate your help

I think what you're asking is for a vector with the second digit of the values in y?

Here's a fixed version of your code:

ID =[2003;2201;3350;9123;8234;1234];

for i = 1:length(ID)
    y = num2str(ID(i));
    out(i) = str2num(y(2));
end
disp(out)

     0     2     3     1     2     2

Here's a better way:

out=double(extract(string(ID),2))';
disp(out)

     0     2     3     1     2     2
