Delete characters that repeat more than 3 times total, or more than 3 times in a row?

Hi Ebtesam,
If you want to delete any character which is repeated three or more times in a row, you can substitute the @unique function in your cellfun() with a regexp that searches for 3+ character matches and replaces them with nothing:
f = @(s) regexprep(s, '(\S)\1\1+', '');
cellfun(f,Input,'UniformOutput',0)
If you need to eliminate characters that occur 3 or more times throughout the whole string, I would recommend writing a separate function that accomplishes that goal and then applying it to each string using cellfun().
Hope this helps!
