An array in which I(1,1) = 0 I(1,2) = 1 and so on till I(256,256) = 65535 using loops

Why bother using loops? What a waste of MATLAB's abilities! The simplest, fastest, and neatest solution is to simply use reshape, as per Andrei Bobrov's last solution:
I = reshape(0:65535,256,[])';

I = zeros(256,256);
k = 0;
for i1 = 1:256
for i2 = 1:256
I(i1,i2) = k;
k = k + 1;
end
end
or
I = zeros(256,256);
k = 0;
for i1 = 1:numel(I)
I(i1) = k;
k = k + 1;
end
I = I';
or without loop
I = zeros(256,256);
I(:) = 0:numel(I) - 1;
I = I';
or
I = reshape(0:65535,256,[])';
