What about a nice loop:
S=['F' 'D' 'C' 'D' 'C';'C' 'C' 'F' 'D' 'F'];
x = sort(unique(S));
fprintf('%c\t', x')
fprintf('\n')
for ii = 1:size(S, 1)
for jj = 1:length(x)
temp(jj) = length(find(S(ii, :) == x(jj)));
end
fprintf('%d\t', temp);
fprintf('\n')
end

temp(ii) is 1,temp(jj)is 2
ii loop calculates the row of origal value(S),and jj calculates the column unique variables

S = ['F' 'D' 'C' 'D' 'C';'C' 'C' 'F' 'D' 'F'];
NumVars = length(unique(S));
