   if length(v) == length(unique(v))
        % There are no repeats.
        .......

You can simply craete a copy of the vector with the required amount of values. There can be other ways around also. Just a suggestion.

@Larissa Monjaraz I don't understand because you forgot to provide your example with actual numbers. So about all I can say is to try ismember().
