Adding values of each row

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

[Voss]

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
