Averaging elements for a cell within a cell array

2 views (last 30 days)
I have a 200×1 cell array where each element is {130×1 double}. How do I take the mean of every element in each cell-within-the-cell? The first element, second element, and so on? So that I have a vector that is 130 x 1 of all the averages?

In order to apply a function on each cell of a cell array, you can use the function cellfun(). Refer to the below documentation on how to use it:
For your question of taking mean of each element in the cell array you can use the code snippet below:
A = cellfun(@mean,C) % C is your cell array and A is the resultant array

That takes the mean for all 200 cells. I want the mean for all the first elements in the 200 cells, all the second elements, all the third elements, and so on. So in the end the vector should be 130 x 1.

where c is your cell.
clc
c={[1,2,3];[2,3,40];[34,21,35];[2,7,5];[33 67 89]};
p=[];
n=size(c{1});
m=size(c);
for i=1:n(2)
sum=0;
for j=1:m(1)
arr=c{j};
sum=sum+arr(i);
end
p=[p sum/m(1)];
end
p
