i have an mat2cell A 12*12 blocks cell, each cell there's 8*8 pixel. then i have mat2cell B 8*8 blocks cell wih each cell there's 8*8 pixel. i want to make operation that every cell in mat2cell B add with whole cell in mat2cell A.

A = mat2cell(x, [8 8 8 8 8 8 8 8 8 8 8 8] , [8 8 8 8 8 8 8 8 8 8 8 8]);
B = mat2cell(y, [8 8 8 8 8 8 8 8] , [8 8 8 8 8 8 8 8]);

To check: you want A{1,1} to be added to each cell B{1,1}, B{1,2}, B{3,5} and so on? And you want A{1,2} the same, producing another set of answers? So the overall result should have numel(A) times numel(B) results, each 8 x 8 ?

What shape do you want the result to be? 4 dimensional? R{P,Q,R,S} = A{P,Q} + B{R,S} ?

I must admit that it is not obvious to me how such a computation would be of value.

yes, it's true. the output just one value. after the add operation, i want to sum it. example, A{1,1} to be added every cell B{1,1} and sum every pixel, so the final value is just one value.
