I have a 1*8 cell array, each martrix in the cell array is 814*1294*40. I want to take the average of each element over the 8 arrays.

Each of the 8 matrix are temp values in the x,y and the 3 dimension is depth. So i am seeking to to average each x,y element over the 8 arrays at each depth, resulting in one 814*1294*40 array.

Thanks

Belinda

在 MATLAB Online 中打开

% make dummy data 
N = 8 ; 
for i = 1:N
  C{i} = rand(2,2,3) ; 
end
% get the mean 
N = length(C) ; 
[m,n,p] = size(C{1}) ; 
themean = zeros(m,n,p) ; 
for i = 1:N
  themean = themean+C{i} ; 
end
themean = themean/N ;
