I tried c = {'',[],'1','2',{'a','b','c',{'x','y','z'},'r'},[123],@isempty} but it's not flatted.
You use "cellfun(@(c) ~isempty(c), cell_array)" and "cellfun(@isempty, c)". While the 2nd method is more efficient, the built-in commands defined as string are still faster, because they do not call Matlab from the MEX level: "cellfun('isempty', c)".
"cat(1, c, ctemp(:)" is faster than the elementwise extraction and re-combination "c = [c{:}, ctemp{:}];".
