Hello,
Is there a way to do a matrix that will accumulat my resoult?
for example:
I have month 1 with value 1
month 2 with value 2
month 3 with value 3 and so on.
In the matrix I want to get for month 1 the value 1. for month 2 the
value 3 (the sum of month 1 and 2) and for month 3 the value 6 (month 1
+ 2 + 3).
I know that I can get the value from row above with "previous" function but I need here the previous column.
Thanks.
