basic question: how do i keep counting up numbers in a vector?

for example i have a vector A=[2 3 2 3 2 3] and i want that every number counts up ?periodically? so i get B = [2 5 7 10 12 15]. i want to do this with some of my data so i can plot it on the Y axis of a graph. what am i supposed to call this way of processing and what would the code look like.

>> a = [2 3 2 3 2 3];
>> B = cumsum( a )

B =

       2     5     7    10    12    15
