how to append inside cells in a cell array without looping?

Question

I have an array

A={1 6 31 65; 1 38 53 4};

I want a cell array in the form

C={[1 1] [6 6] [31 31] [65 65];[1 1] [38 38] [53 53] [4 4]}; 

One way of doing this is by looping:

for count=1:2
    for i=1:4
        for j=1:2
            C{i,j}(count)=A(i,j);
        end
    end
end

How can I do this without looping and improve time complexity?

Edit: It is not the case for just count=2, I've application where count goes as high as 85. Looping greatly reduces efficiency. And going for higher dimension matrices is also inefficient.

One way to do this would be to use cellfun to create each new element

C = cellfun(@(x)ones(1,2) * x, A, 'UniformOutput', false);

As @excaza has pointed out though, you have data of equal sizes so it is recommended that you use a multi-dimensional array instead. You could (for example), just replicate the data along the third dimension instead

C = repmat(A, [1 1 2]);
