Hi, I think what you're trying to do can be accomplished without reshaping the multi-dimensional matrix.
% Initializing 20x30x40 matrix of random elements
X = rand(20,30,40);
% Splitting the matrix into 2 sets based on the alternating third dimension
% The two sets are of dimensions 20x30x20 each.
% Taking out odd elements of third dimension
setA = X(:,:,1:2:40);
% Taking out even elements of third dimension
setB = X(:,:,2:2:40)
% Adding the two sets A and B
result = setA+setB;
The key here is splitting the main matrix into two 'pages' that you actually want to add.
