X=[1 3 3 3 3; 3 7 4 4 4; 4 7 5 5 5; 5 9 8 8 8 ];
c = unique(X(:));
z = histc(X(:),c);
out = sortrows([c,z],2);

Is this homework? Sounds like it. Why not try histcounts()? Or histc if you have an old version of MATLAB. It's a good chance to learn about histograms and the several MATLAB functions related to histograms.
