I am a having cell

C=5x1 cell

which contains

10x2 double
10x2 double
10x2 double
10x2 double
10x2 double

I need to find the difference between first and second column of C. Could anyone please help me on it.

cellfun(@(x) x(:,1)-x(:,2),C,'UniformOutput',false)

ok. As a next step I calculated the sum using

cellfun(@sum, C,'UniformOutput',false)

Now I want to divide by 10.

So i tried using

cellfun(@sum, C,'UniformOutput',false)/10

but i am getting error stating Undefined operator '/' for input arguments of type 'cell'.

Could you please help me to overcome the error.

If you do the sum and then divide by 10, so I guess you want to calculate the mean and you can use the following directly without doing the sum

cellfun(@mean,previous_result,'UniformOutput',false)

Sorry, I made a mistake. First I need to square it and then sum it together and divide by 10. Could you please help me on it.

I used the command

D=cellfun(@(x) sum((x(:,1)-x(:,2)).^2)/10,C,'UniformOutput',false)

Now I want to sum D and divide by 5.

Could you please help me on this.

mean(cell2mat(D))
