sum of series

Hello to all I need to calculate the sum of series: S= (Vx+1 - Vx)+(Vx+2 - Vx)+ (Vx+3 - Vx)+ (Vx+...-Vx) while x changes and increases form 1 to 12 x=1:12 How to do it right and elegant? Thanks a lot.

I think you may need to try and ask your question more clearly. What you've written there reduces to 1 + 2 + 3 + ...

If it's an infinite sum, it obviously diverges, if not it's just n*(n+1)/2

I think the x+1, x+2 etc. are subscripts (indexes) of his V array.

What we need here is LaTeX markup :)

Sounds like a homework problem. So you need to look up sum(V(1:12)) or cumsum(V(1:12)) - that should give you a big hint.
