How to sum field elements inside a large structure array.

I have mat. data file with the follwoing spes:
data=load('load_models.mat', 'models')
data =
struct with fields:
models: {1000×1 cell}
>> models
models =
1000×1 cell array
0 {1440×3 double}
1 {1440×3 double}
: :
999 {1440×3 double}
Each cell of the 1000 rows contais (1440×3) matrix.
What I want to get is a new array of size (1440×3), where the elemnts of the new array is the summation of corresponding individal feild elements of the whole 1000×1 struct.
Any fuction of example approch can help me achive my opjective?

Try mean() and cell2mat(). If that does not work, can you attach your .mat file with the paperclip icon (if it's less than 5 MB in size).

Mean() and sum() didn't work. The cell2mat reshape the aray to size (1440000 x 3). the new array size I want is (1440×3) where the 1440 represnet the # of minites in a day and 3 columns values are the cofficents of the some models.
Does this work for you:
fileName = 'active_power_load_models.mat'
s = load(fileName)
ca = s.p_zip_models;
theSums = zeros(1440, 3);
for k = 1 : length(ca)
thisArray = ca{k};
theSums = theSums + thisArray;
end
