This is very similar to your previous question: http://www.mathworks.com/matlabcentral/answers/33405-counting-the-values-and-variables

What have you tried so far? Where are you stuck?

Answer 1

[Andrei Bobrov]

a = unique(A);
out = [a, histc(A(:),a)];

OR in rows:

a = unique(A)'
outrws = [a;cell2mat(arrayfun(@(x)histc(A(x,:),a),(1:size(A,1))','un',0))]

in columns

a = unique(A)
outcls = [a,cell2mat(arrayfun(@(x)histc(A(:,x),a),1:size(A,2),'un',0))]
