optimizing for loop that is been called often

2 views (last 30 days)
can this loop be optimized? It is called 1m times and is the only thing I couldn't optimize yet.
Oper_year=1:1:Lifetime;
[costM,PVcost,YearProd,Elcost]=deal(zeros(size(Oper_year)));
for j=1:1:length(Oper_year)
if j==1
costM(j)=Mcost*PVprice*PVP;
PVcost(j)=PVprice*PVP+Bcost;
YearProd(j)=sum(PMDb)*PVP;
Elcost(j)=Elprice;
Bcost(j)=Bcost;
else
Bcost(j)=Bcost(1)*(1+bank*Oper_year(j-1));
costM(j)=PVprice*(Mcost*(1+Minf)*(Oper_year(j-1))+Mcost)*PVP;
PVcost(j)=(PVprice*PVP)*(1+bank*Oper_year(j-1))+Bcost(j);
YearProd(j)=sum(PMDb)*PVP*((1-PVdeg)*Oper_year(j-1)+1);
end
end
thanks

Elcost(1)=Elprice;
Bcost(1)=Bcost;
Bcost(2:end)=Bcost(1)*(1+bank*Oper_year(1:end-1));
costM(2:end)=PVprice*(Mcost*(1+Minf)*(Oper_year(1:end-1))+Mcost)*PVP;
PVcost(2:end)=(PVprice*PVP)*(1+bank*Oper_year(1:end-1))+Bcost(2:end);
YearProd(2:end)=sum(PMDb)*PVP*((1-PVdeg)*Oper_year(1:end-1)+1);

I got the point, I will see if it will be faster than the existing code. Thanks
