Removing replication in matlab
4 views (last 30 days)
Hi guys, I have string like this
I want to remove replication of zero and ones in that string this means , the output would be like this '010101010101' without replication of zero or ones ... *be careful that I dont know number of replication of zeros or ones in the str string ...
any help please how can I do that in matlab? thanks alot.

But the string, after you remove the replicates will always be identically the same, just alternating 0's and 1's. If the first element is a '0', then the string will be '010101010...'. If the first element is a 1, then it will be opposite. The only question is the length of the string.
My point is, don't even worry about removing the replicated elements. Just create the final result as it must be.
newstr = str(1);
if newstr == '0'
% Count the number of '10' transitions
newstr = [newstr,repmat('10',[1,numel(strfind(str,'10'))])];
% was the final element a '1'
if str(end) == '1'
newstr = [newstr,'1'];
% then the first element was a '1'
% So count the number of '01' transitions
newstr = [newstr,repmat('01',[1,numel(strfind(str,'01'))])];
% was the final element a '0'
if str(end) == '0'
newstr = [newstr,'0'];
For example, with str as in your example, this produces:
