Adding elements of 3D matrices

Hi all,

Suppose A(10,10,3) and I need to add the elements of A to get B(10,10,1) such that B(1,1,1) = A(1,1,1)+A(1,1,2)+A(1,1,3); B(1,2,1) = A(1,2,1)+A(1,2,2)+A(1,2,3); B(2,2,1) = A(2,2,1)+A(2,2,2)+A(2,2,3); and so on. This without using for loop.

Regards N. M. Syed

B = sum(A,3);

Answer 2

a(:,:,1)=[1 2 3;4 5 6;7 8 9];
a(:,:,2)=[1 2 3;4 5 6;7 8 9];
a(:,:,3)=[1 2 3;4 5 6;7 8 9];

b=a(:,:,1)+a(:,:,2)+a(:,:,3)

or

b=sum(a,3)
