Cumulative Frequency

When I do a calculation with a cumulative frequency, for example:

S2 %Column vector

B=[];

for i=1:length(S2)-1

    B(i)=S2(i)+S2(i+1);
    Total=sum(B);

end

When I try and display "Total", it always ends up with the whole cumulative array instead of just displaying the total itself.

Is there a simple way to display the total without displaying anything else? Thanks in advance.

I am not sure what you want Total to be, but you do not need the loop ...

S2 = randn(10,1);
B = S2(1:(end-1))+S2(2:end);
Total = sum(B)
