hey guys i am trying to find a sum of cashflows based on 4 different scenarios. This is my code and I can only run the program and get a solution from net_income_1. The other 3 net_incomes are returned as undefined. Any ideas?
xin(1) = 500;
xin(2) = 427;
FIT = 12.1;
Xe = 3.1;
RHI = 3;
Pth = 3;
fuel = xin(1)*2.13;
maintenance = xin(1)*0.5;
Pe = 6.5;
Le = xlsread('hourly electric demand.xlsx');
Lth = xlsread('hourly thermal demand.xlsx');
for j=1:1
for i=1:24
if xin(1)>= Le(j,i) && xin(2)>=Lth(j,i);
Feed_in_tariff_1 = Le(j,i)*FIT;
exported_electricity_1 = (Le(j,i)-xin(1))*Xe;
Heat_incentive_1 = Lth(j,i)*RHI;
avoided_electric_1 = Le(j,i)*Pe;
avoided_thermal_1 = Lth(j,i)*Pth;
income_1 = Feed_in_tariff_1+exported_electricity_1+...
avoided_electric_1+avoided_thermal_1+Heat_incentive_1;
expences_1 = fuel+maintenance;
net_income_1 = income_1-expences_1;
elseif xin(1)<=Le(j,i) && xin(2)<=Lth(j,i);
Feed_in_tariff_2 = xin(1)*FIT;
Heat_incentive_2 = (Lth(j,i)-xin(2))*RHI;
avoided_electric_2 = xin(1)*Pe;
avoided_thermal_2 = xin(2)*Pth;
electric_purchase_2 = (Le(j,i)-xin(1))*Pe;
thermal_purchase_2 = (Lth(j,i)-xin(2))*Pth;
income_2 = Feed_in_tariff_2+ Heat_incentive_2 + avoided_electric_2 + avoided_thermal_2;
expences_2 = fuel+maintenance+electric_purchase_2+thermal_purchase_2;
net_income_2 = income_2-expences_2;
elseif xin(1)>=Le(j,i) && xin(2)<=Lth(j,i);
Feed_in_tariff_3 = Le(j,i)*FIT;
Heat_incentive_3 = (Lth(j,i)-xin(2))*RHI;
exported_electric_3 = (Le(j,i)-xin(1))*Xe;
avoided_electric_3 = xin(1)*Pe;
avoided_thermal_3 = xin(2)*Pth;
thermal_purchase_3 = (Le(j,i)-xin(2))*Pth;
income_3=Feed_in_tariff_3 + exported_electric_3 +...
Heat_incentive_3 + avoided_electric_3 + avoided_thermal_3;
expences_3 = fuel+maintenance+thermal_purchase_3;
net_income_3 = income_3 - expences_3;
else
if xin(1)<= Le(j,i) && xin(2)>= Lth(j,i);
Feed_in_tariff_4 = xin(1)*FIT;
Heat_incentive_4 = Lth(j,i)*RHI;
exported_electric_4 = 0;
avoided_electric_4 = Le(j,i)*Pe;
avoided_thermal_4 = xin(2)*Pth;
electric_purchase_4 = (Le(j,i)-xin(1))*Pe;
income_4 = Feed_in_tariff_4 + exported_electric_4 +thermal_purchase_4...
+ Heat_incentive_4 + avoided_electric_4 + avoided_thermal_4 ;
expences_4 = fuel+maintenance+electric_purchase_4;
net_income_4 = income_4 - expences_4;
end
end
end
end
final = net_income_1 + net_income_2
Thanks

I'm not positive, but I'm pretty sure there's a way through your decision tree that doesn't define them. The last outer else forces you into an inner if with no else so when it fails that inner if they're left undefined.
