Inverse/opposite of diff function?

I have a 480x640 matrix and would like to perform the diff function on the elements but instead of subtracting the previous element I would like to add it.
I have tried using x(2:end) + x(1:end-1) Which return the right values but instead of returning a 479x640 matrix it returns a 1x307199 matrix. How can I change the function to give the 479x640 matrix.
Thanks in advance

Example:
>> A = randi([1,5],1,5)
A =
1 3 5 2 1
>> B = diff(A)
B =
2 2 -3 -1
>> C = cumsum([A(1) B])
C =
1 3 5 2 1
