Sum of arrays - correct procedure

I have four columns (e1,1; e1, 2; e2,1; e2,2) and I would like to develop matlab code to calculate the following: sum(1:5,1:2)+sum(1:5,3:4). There is a code that I used in berkeley madonna (arraysum[]) for this operation but i am not sure what the comparable feature is in matlab.

Thanks in advance.

Two questions to clarify:

How are your four "columns" currently stored? Do you mean you have four separate variables? Or is e1 a 5x2 array and e2 also a 5x2 array? Or something else?

For the example you give, what is the correct final answer?

These things may seem clear or obvious to you, but you need to explain them to us.
