Hi,

I have a 3x3xn Array which actually contains n times 3x3 matrices. I want to convert it to a one dimensional cell array with n entries (nx1) so that the ith cell contains the ith 3x3 matrix. I know that the key functions to use are 'mat2cell' and 'num2cell' but I can't get it right. It is important that the cell array will be only one dimensional because it should enter to a 'table' as one of the fields.

Any help will be appreciated! Alon

在 MATLAB Online 中打开

Use the mat2cell function:

M = randi(9, 3, 3, 2)                                   % Create Matrix
Msz = size(M);                                          % Get Size
C = mat2cell(M, Msz(1), Msz(2), ones(1,Msz(3)));        % Convert To Cells, One ‘Page’ Per Cell
C{1}                                                    % View Output (Optional)
C{2}                                                    % View Output (Optional)
