Did you see, that the question looks funny without a proper formatting? I've marked the matrices and hit the "{} Code" button to make the question readable.
What should happen, when large values appear?

If it is 4*4 matrix
- 1 2 3 4
1 1 0 0 0
2 0 1 0 0
3 0 0 1 0
4 0 0 0 1

A=[1 2 3
40 5 6
7 800 9];
format = sprintf('%%%d',max(floor(log10(A(:)))+1));
fprintf([format 'c '],'-');
fprintf([format 'd '],1:size(A,2));
fprintf('\n');
for rowN=1:size(A,2)
fprintf([format 'd '],[rowN, A(rowN,:)])
fprintf('\n');
end
- 1 2 3
1 1 2 3
2 40 5 6
3 7 800 9
