Hi everybody,
I would like to sum multiple matrice using a loop.
I attach my data.
So, I have a multiple 4D double structure, that contains 4x4x32x12 matrices.
I would like to sum all the matrices according the last argument to obtain 12 matrices which are the sum of the 32 matrices (in my code i = 1:12 ; j = 1:32).
I think I have to use a loop.
Is anybody could help me?

Is this what you want?
result = squeeze(sum(T3,3));
If not please clarify what the dimensions of the final result should be.

The dimension of the final matrice is correct 4x4x12 but it doens't correspond to the addition of all matrices.
I try to explain in other words. I would like to realize an addition of the first 32, and next 32 etc... and stock this result in a new 4x4x12 matrice.

That is what I believe I gave you...
If we index the array as T(i,j,m,n) are we summing across m or something else?
