3D array to cell array

If I had a 3D array of 550x129x3, how would I transform this into a cell array consisting of 3 cells in the array which contains 550x129 corresponding to it? I looked at the num2cell documentation and it doesn't mention how to organise it into that format.

Use the mat2cell (link) function:

A = rand(550, 129, 3);                                          % Create Matrix
C = mat2cell(A, size(A,1), size(A,2), ones(1,size(A,3)));       % Cell Array
Check = cell2mat(cellfun(@size, C, 'Uni',0))                    % Check (Delete Later)

producing:

Check(:,:,1) =
   550   129

Check(:,:,2) =
   550   129

Check(:,:,3) =
   550   129
