Read about cell2mat and _sum)

A{1} = rand(2,1) ;
A{2} = rand(2,1) ;
A{3} = rand(2,1) ;

B = cell2mat(A) ;
sum(B)

You can achieve the above in many ways. Like using loop or cellfun.

When i am using loop then it shows out of memory while i have 12 gb RAM.Thank for your suggestion.I will try your solution if it will working then good.

64*(12*10^8)/(8*2^30) = 8.9407 GB

So, change the class if that's OK.

Use the same name for your variables and ...
