Hi! I have a sting 'aaaaaaabccccbbbdcccccaaaa' and I want to trasform it in 'abcbdca': I want to have only one of the consecutive equal value. Can you give me some suggests? Thanks

s = 'aaaaaaabccccbbbdcccccaaaa'
new_s = regexprep(s, '(.)(\1)+', '$1');

@pamela sulis: read the regexp documentation to learn the answer to your question: it describes the input str as "Input text, specified as a string or a cell array of strings." Struct is not listed.
