Try following this approach:
Convert vector to string using sprintf. Use regexp to search for repeating 1's. Replace the 1's for 0's except second one.
Try this code:
str = sprintf('%d',vector_name);
[start_index,end_index] = regexp(str,'11[1]*');
str(start_index) = '0' %converting the first 1 of repetition to zero
idx = find(end_index == start_index+1) % we check for double 1 occurence because we don't need to replace at that location
start_index(idx) = [];
end_index(idx) = []; % remove the double 1 occurence indices
str(start_index+2:end_index) = '0'; % converting to 0's for the other patterns
Hope this helps.
