Voluminas out of AUC of Flow,time graph

Hello,

very new to matlab and basic programming. I've got a dataset of flows over time with regular intervals. I need for each interval the moved volume and so I would like to calculate the AUC for each time interval and so generate a new dataset with these volumina. I only got as fas as to calculate the entire AUC with trapz(t,Q), but I need to know the AUC for each interval. Can anyone help?

Solved with:

>> Z = zeros(170, 1)

for i = 1:(size(Qao, 1)- 1)

Z(i) = trapz(t(i:i+1), Qao(i:i+1))

end

only problem was that Z was printed 170 times, but we've got our data!
