Please stop asking the same question repeatedly. Asking the same question over and over again will not get you a better answer.

Here is a start for you. It might be easier to construct the loop using backwards indexing. E.g.,
n = 6;
for k=n:-1:1
% Insert code here for your number
end
So you need to fill in the loop above. E.g., when k=6 at the first iteration, how do you form the number 123456? Then when k=5 in the next iteration, how do you form the number 12345? Etc. Maybe you can think of a vectorized way to do this, or maybe you can think of another loop to do this. If you are stuck with how to code this, try to think of how you might do it by hand first. Then come up with a pattern that you can code up.
