str='aaaaddccccfeeee'
[ii,jj,kk]=unique(str)
freq=histc(kk,1:numel(ii))
c=regexp(ii,'.','match')'
out=[c num2cell(freq)]

To count the occurrences of a specific character in a string in MATLAB, you can use the count function.
str = 'aaaaaddddccceeeeee'; % The string to search
characterToCount = 'a'; % The character you want to count
% Count the occurrences
occurrences = count(str, characterToCount);
% Display the result
fprintf('The character "%s" appears %d times in the string.\n', characterToCount, occurrences);
Output
The character "a" appears 5 times in the string
