3D matrix summation

If I have the following 3D matrices. How I sum every T(:,:,1) with its following T(:,:,2) to have 3 2D matrices.
T(:,:,1) =
0 0 0 0 0 0 0 0 0 0

Your question is unclear. Is there only one 3D array called T? Or do you have several of these arrays? Can you be more explicit in what output you want? I.e., other that simply doing T(:,:,1) + T(:,:,2) is is not clear to me what you want.

@Mahmoud: Please answer James' question: What is wrong with T(:,:,1) + T(:,:,2)?

For any one of them,
sum(T, 3)

Hello,
How can I add in 3D using intervals;
example:
(62x50x341) 3d matrix
I want to add the following intervals in 3D:
Intervals; 8,30,31,31,30,31,30,31,31,28,31,29
is it possible to do it in a loop?
Thanks in advance
