MATLAB: How to convert cell arrays inside a cell to matrix

cell arrayscell2mat

I have a cell which contains another cell which contains another cell in it. I want to convert the most inside cell to matrix but using cell2mat is not working as it is saying "CELL2MAT does not support cell arrays containing cell arrays or objects."
Any other function or some idea how to convert inner cell arrays to matrix?
Thank you.

The exact solution depends on how the data is structured inside the nested cell arrays. The following code shows an example
C = {{{[1 2 3]}}, {{[4 5 6]}}, {{[7 8 9]}}};
C1 = [C{:}];
C2 = [C1{:}];
C3 = [C2{:}];
