How can I fill column elements with the column number. First column contains only 1, second only 2, third only 3, etc.

Is it possible to do this without cycle? I mean without 'for'?

m=5;% m is length of columns
n=4;% n is number of columns
for i =1:n 
    A(:,i)=ones(m,1)*i ;
end 
A =

     1     2     3     4
     1     2     3     4
     1     2     3     4
     1     2     3     4
     1     2     3     4

m=5;
n=4;
i =1:n; % n is number of columns
A(:,i)=ones(m,1)*i ;% m is length of columns
  % Yes it is

A = ones(m, 1) * ii 
%or
A = repmat(ii, m, 1)
