MATLAB: N x 1 array, add row-wise

Question

Hello all,

i've got an 832×1 array with distances in meter, looking like that:

1
3
4
5
3
8
3

How do i add up those distances row-wise to get something like that:

1
4
8
13
16
24
27

I read through the 'sum' help but could not find the right answer. Nevertheless it should be a 1 second task..

Thanks in advance!!
