You didn't say what you expect, and the code is so wrong in so many ways that I can't figure out what you want. So I made this attempt.
d11 = cell(6,6);
d = num2cell(rand(6))
[rows, columns] = size(d11);
for col = 1 : columns
for row = 1 : rows
thisCellContents = [d{row, col}; zeros(rows, 1)];
d11{row, col} = thisCellContents;
end
end
celldisp(d11)
Is it what you want?
