How to add two cell arrays of the same dimensions

I have two cell arrays A and B, each of size 1x5 cells. Each cell is a row vector with different size (A{1}=B{1}=1x4 vector, A{2}=B{2}=1x5 vector...) where each cell in A is the same size of the corresponding cell in B. How can I add A+B?

Try this:

A = [{rand(1,4)} {rand(1,5)}];
B = [{rand(1,4)} {rand(1,5)}];

Out = cellfun(@plus, A, B, 'Uni',0)

This doesn't work when I try to add three cell arrays, is it possible to add three at once?

[Star Strider]

No. You can only add two at a time this way.

To add the third:

A = [{rand(1,4)} {rand(1,5)}];
B = [{rand(1,4)} {rand(1,5)}];
C = [{rand(1,4)} {rand(1,5)}];

Out = cellfun(@plus, A, B, 'Uni',0)
Out = cellfun(@plus, Out, C, 'Uni',0)

Long and sad, but thank you again for your help.

You can always put that in a loop if you have several cells to add, or use the arrayfun function that does the same thing (although less efficiently).

Unless you already coded the game board (if so, you need to post the code), that is going to require some time to write. The design of that code is not immediately obvious to me.
