How to access the contents of inner cells in a cell??

I want to access the contents of inner cells of a cell... what is its syntax??. e.g I have a cell named "fold{j}" that contains the cells in it named with "inner_cell{i}"

i.e. each fold contains four inner_cell in it....

Now what should I do e.g. if I want to access the contents of "inner_cell{3}" of fold{2} ??....

What does this have to do with pattern recognition (like your tag suggests)?

 x = cell(2,1);
 x{1} = cell(3,1);
 x{1}{1} = randn(3,1);

Now to access

x{1}{1}

Note

x{1}{2} % is empty
