Hi, I am trying to add values on each row, for example, I have 53X1 data, I want to add 1st row value to 2nd row value, so that my 2nd row value is the added value, and this continue until the last value. May I know how to code that?
Row : Value
1 : 1
2 : 3
3 : 6
4 : 8
I want it to become
Row : Value
1 : 1
2 : (3+1 = 4)
3 : (4+6 = 10)
4 : (8 + 10 = 18)
thank you very much

Ran in:
data = [1;3;6;8]
data = 4×1
1 3 6 8
result = cumsum(data,1)
result = 4×1
1 4 10 18
Or, if you want to overwrite your data with the new value:
data = cumsum(data,1)
data = 4×1
1 4 10 18
