for some reason i cant get Sum() to work.
i have two arrays
z [0, 1, 1, 0, 1, 0, 0, 1, 1]
p [1, 0, 1, 1, 1, 1, 0, 1, 0]
what i'm trying to do is calculate:
z/p
which should be 5/6 or 0.83
im trying it like this:
numberofcellsinarray = LastValue(BarIndex()) + 1;
sumZ = Sum(z, numberofcellsinarray);
sumP = Sum(p, numberofcellsinarray);
result = sumZ/sumP;
but this wont display anything in the automatic analysis window
can anyone suggest a good way to do this?
