I have a cell array A of dimension 1x22 each cell having different number of elements with compulsory 2 columns. for example A{1,1}= [ 23 34; 44 55; 56 71; 63 49; 71 30]
A{1,2}= [12 13; 10 99] and so on. Now, I need a matrix which has maximum number of columns equal to 44(twice the number of cell array columns) and rows equal to the maximum number of columns of all the cells. Here, it is 5(from A{1,1}) NaN or 0 values do not matter in my case.

nCol = cellfun('size', A, 1);
nRow = numel(A) * 2;
Output = NaN(max(nCol), nRow);
But I guess you want to insert the values of the cell also. Then:
for iA = 1:numel(A)
idx = (iA - 1) * 2 + 1;
Output(1:nCol(iA), idx:idx+1) = A{iA};
end
