Swap shape of cell array full of arrays

C = {[1,2,3,4,5], [1,2,3,4,5]; [1,2,3,4,5], [1,2,3,4,5]}
C = 2×2 cell array
    {[1 2 3 4 5]}    {[1 2 3 4 5]}
    {[1 2 3 4 5]}    {[1 2 3 4 5]}
F = @(a)reshape(a,1,1,[]);
D = reshape(num2cell(cell2mat(cellfun(F,C,'uni',0)),1:2),size(C{1}))
D = 1×5 cell array
    {2×2 double}    {2×2 double}    {2×2 double}    {2×2 double}    {2×2 double}
D{:}
ans = 2×2
     1     1
     1     1
ans = 2×2
     2     2
     2     2
ans = 2×2

Approach 1

% Example input: an nxn cell array
n = 2;
m = 4; % changed from 5 to 4 to make it reshapeable to 2x2
inputCellArray = cell(n, n);
for i = 1:n
    for j = 1:n
        inputCellArray{i, j} = 1:m; % changed from [1 2 3 4 5] to 1:4
    end
end
% Reshape the input cell array into a 1xm cell array of 1x(n^2) arrays
reshapedCellArray = reshape(inputCellArray', 1, []);
% Use cellfun to reshape each element in the reshapedCellArray into a 2x2 array
outputCellArray = cellfun(@(x) reshape(x, n, []), reshapedCellArray, 'UniformOutput', false);
% Display the resulting 1xm cell array of nxn arrays
disp(outputCellArray);
    {2×2 double}    {2×2 double}    {2×2 double}    {2×2 double}
% Print the values of each 2x2 array
for i = 1:numel(outputCellArray)
    fprintf('Cell %d:\n', i);
    disp(outputCellArray{i});
end
Cell 1:
     1     3
     2     4
Cell 2:
     1     3
     2     4
Cell 3:
     1     3
     2     4
Cell 4:
     1     3
     2     4
