Please give us a small example of what you want. E.g., start with a 2x2x2 array and then show us the resulting 2x2 matrix you want as an output. Maybe all you need is sum(matrix,3) or mean(matrix,3), but we can't tell from what you have written so far.

Here is an example of what i want (only my A is 256*256*256)
>> A
A(:,:,1) =
1 2
3 4
5 6
A(:,:,2) =
7 8
9 10
11 12

[m,n,~] = size(A);
newA = reshape(permute(A,[2 1 3]),m*n,[]).';
