I have five arrays lets say A, B , C , D, E of size 100x 3.
Here, For instance, I have to divide entries in the second column of A by sum of entries in the second column of A, B , C , D , E
Something like this
AA = A (:,2)/ ( A(:,2) + B(:,2) + C(:,2) + D(:,2) + E(:,2))

Use element-wise division ( ./ ) and you'll have it:
AA = A(:,2) ./ ( A(:,2) + B(:,2) + C(:,2) + D(:,2) + E(:,2) )
