Adding SPMD results - no loop

I have some multiple outputs from SPMD, each containing dofferent part of matrix:

finalImage = cell2mat(finalImageAll(1)) + cell2mat(finalImageAll(2)) + cell2mat(finalImageAll(3));

How can I add them all together in a vectorized way (no loop), in one line or so? In this example I show three, but there will be more of them (up to ~50).

% Creating random sample data
finalImageAll{1}=rand(3,3);
finalImageAll{2}=rand(3,3);
finalImageAll{3}=rand(3,3);
finalImageAll{4}=rand(3,3);

% now summing them all up in one line and no loop
finalImage = sum(cell2mat(reshape(finalImageAll,1,1,numel(finalImageAll))),3)

And the results: (it is random numbers so you would get something else)

finalImage =

      2.9640    2.6123    1.1453
      2.6784    1.9987    1.8235
      1.9245    2.1087    3.4398
