How can i simultaneously reference in cells

I have a cell array, lets say C. Each cell contains a matrix.

For example lets say C is

 C{1}=[1 2;3 4;5 6]
 C{2}=[7 8;9 10;11 12]

How can I create a new cell array D, whose i-th element is a matrix consisted by the i-th transposed rows of all matrices in C?

Then D must be

   D{1}=[1 7;2 8]
   D{2}=[3 9;4 10]
   D{3}=[5 11;6 12]

Why do you want the trouble of a cell array when just a normal numerical array would be so much easier?

This is fun... you can try

C{1}=[1 2;3 4;5 6]
C{2}=[7 8;9 10;11 12]
g = @(j)[C{1}(j,:);C{2}(j,:)]'; % function handle
D = arrayfun(g,1:3,'UniformOutput',false); % awesome function

Answer 2

E = cat(3, C{:});
E = permute(E, [3,2,1]);
n = size(E, 3);

D = cell(1, n);  % Faster than CELL2MAT:
for iD = 1:n
  D{iD} = E(:, :, iD);
end

Sorry, I cannot test this currently.

But consider Image Analysts idea: When you operate on rectangulare numerical values, a double array is smarter and much more efficient than a cell.
