Adding three cells element wise using cellfun

Folks,

I have three cell arrays of the form 1*6 each containing an 18*9 double. I have attempted to add each corresponding element in each cell array. Ie the ith element of cell A + ith element of cell B + the ith element of cell C.

D = cellfun(@(x,y,z){x+y+z},A{ii},B{ii}, C{ii});

but i get an error stating

??? Error using ==> cellfun Input #2 expected to be a cell array, was double instead.

Any suggestions? B

The ith element of cell A is a 18x9 array, is it right?

[bugatti79]

A is a 1*6 cell
A{1,1} is an 18*9 double matrix
A{1,2} is an 18*9 double matrix
A{1,n} is an 18*9 double matrix
A{1,6} is an 18*9 double matrix

looking to add the corresponding elements in each matrix.

Answer 1

[Azzi Abdelmalek]

 n=2;
A{n}+B{n}+C{n}

Is it what you are asking for?

% or maybe you want this

ii=5
out=cellfun(@(x,y,z) x(ii)+y(ii)+z(ii),A,B,C)

Answer 2

[Jos (10584)]

D = cell(size(A)) ;
for k=1:numel(A),
   D{k} = A{k}+B{k}+C{k} ;
end

Hi folks,

Adding the cell arrays of the same dimension works after. Thanks for your help.
