Hi FIR,
Make data:
D = [(1:800)' randi(4,800,1) rand(800,1)+99];
Display all data rounded:
disp(round(D))
Display the top two percentages:
[~,sortOrder] = sort(D(:,5),'descend');
disp(D(sortOrder(1:2),:))
If you want it to come out exactly like your question text (ie, without decimal places for the first 4 columns):
fprintf('%5d %d %d %d %0.2f\n',D(sortOrder(1:2),:)')
I don't know what "CV error for 3rd column" means - I think that it's a completely separate question.
