Uwe,
You're going to get a lot of answers to this.
FoldList[Plus, 0, {1, 2, 3, 4, 5}]
{0, 1, 3, 6, 10, 15}
If you don't want the leading zero...
Drop[FoldList[Plus, 0, {1, 2, 3, 4, 5}], 1]
{1, 3, 6, 10, 15}

Hello,
I would like to compute the cumulative sum for a list, but do not find
the command.
For
{1,2,3,4,5}
I would like to get
{1,3,4,10,15}
Is there nothing builtin in Mathematica? I already looked in lists and
matrices and Google...
Uwe
