Cumulative sum along an axis

Hi all,
I would like to calculate the cumulative sum in COMSOL without exporting data to Matlab. How can I achieve this ? Let's say my values are y(x) = [0,1,2,3,4,5] and I would like to get cumsum(y) = [0,1,3,6,10,15].
A push in the right direction would be highly appreciated :)

Hello Christian,
This blog, and in particular the section on the anti-derivative, should help:

Hi Jeff,
many thanks, its a lot clearer now and I was able to implement it using the steps described in a follow-up blog post:
