adding same size cell arrays

Assume I have a matrices C1,C2 as follows:

C1 = nx1 cell each cell is [5x5 double].

C2 = nx1 cell each cell is [5x5 double].

How to calculate C3 as:

C3{1,1} =  C1{1,1}+C2{1,1};
C3{2,1} =  C1{2,1}+C2{2,1};
          .
          .
C3{n,1} =  C1{n,1}+C2{n,1};

using cellfun or any other method without looping

Answer 1

cellfun(@plus,A,B,'uni',0)
cell2mat(A)+cell2mat(B)

[Alnazer]

Just to clarify; your answer provides two ways to solve the problem;

C3 = cellfun(@plus,A,B,'uni',0);

Result in C3 a cell array, while

C3 = cell2mat(A)+cell2mat(B);

Result in C3 as array type double.

am l right??

[dpb]

Yes altho the latter is easily converted simply by enclosing in the curlies...

C3 = {cell2mat(A)+cell2mat(B)};

Which might have a performance advantage I've no idea...

If you have the neural networks toolbox:

gadd(A,B)
