One way of doing it:
tableau_string = {'3.5' 'alain' '3.5' 'alain'; 'alain' '' 'alain' 'test'; '' 'test' '' 'test'; '5' 'test' '5' 'test'};
[strings, ~, position] = unique(tableau_string(:));
count = accumarray(position, ones(1, numel(tableau_string)));
stringcounts = [strings num2cell(count)] %if you want it all in a cell array
You could use histc or hiscounts instead of accumarray for the same result.
