ADD

c - your matrix "of flows"

dt = .5 % eg .5 sec
timeColumn = dt*(0:size(c,1)-1).'

thanks, ill look at that later but I was thinking of using an estimation using summation that its equal to sum*dt would there be a simple way of doing this? I have a matrix of flows and want to use one column of them and find the area of the graph of that column vs. time
