subsums

[Gorazd Brumen]

Hi,

How do you form a vector of subsums of a certain vector without the for 
loop?
Example:
Let x = [1 2 3 4 5 6 7 8 9 10]
I want to get a vector that would have as entries
sum([1 2 3 4 5]) and sum ([6 7 8 9 10])?

Or is the solution with the for loop not slower?

Thanks,
g.
