Hi Ian,

Can you post the code that you tried and what the issue was or what didn't work? From that equation it is not straight forward as what the values of each variable be.

Regards,

Sriram

totalcost(pgridbuy, pricebuy, deltatimebuy, pgridsold, pricesell, deltatimesell);
function totalcost(pgridbuy, pricebuy, deltatimebuy, pgridsold, pricesell, deltatimesell)
   TClist = [0, 0, 0, 0, 0];
    for i = 1:length(TClist);
        buy = pgridbuy(i) * pricebuy(i) / deltatimebuy(i);
        sell = pgridsold(i) * pricesell(i) / deltatimesell(i);
        TClist(i) = buy - sell
    end

This does what you seemed to be trying to do::

pgridbuy = [3.3, 3.5, 3.2, 3.1, 3.6];
pgridsold = [2.3, 2.6, 3.1, 4.1, 4.4];
pricebuy = [2400, 2400, 2400, 2400, 2400];
pricesell = [1300, 1300, 1300, 1300, 1300];
deltaT = 1;
TC = sum(pgridbuy.*pricebuy - pgridsold.*pricesell )/deltaT;
disp(TC)

I assume that, in general, you will not want all the values of pricebuy and pricesell to be the same.
