I have two houses, House 1 and house 2. Each house has one or two Electric Vehicles(EV), each EV has its own specific ID number. I want to find how much more max power House 1 and House 2 are jointly demanding when EVs are introduced. So far I have used for loops like this:

Vehicle1{jj}, Vehicle2{jj2} and HH2 are of the size 525600x1 double: the power demand every minute of the year

In this example there are 3 available vehicles, so the Vehicle and VID cells will both have the size 3x3

%Vehicle1 - electricity consumption of House 1s vehicle(s)    
%Vehicle2- electricity consumption of House 1s vehicle(s) 
%VID1 - ID number of vehicle(s) for House 1
%VID2 - ID number of vehicle(s) for House 2.
%HH2
for jj=1:numel(VID1)
        V11=Vehicle1{jj};
        ID1=VID1{jj};
        for jj2=1:numel(VID2)
           
           V22=Vehicle2{jj2};
           ID2=VID2{jj2};
%Removes all doubles (House 1 and House 2 cannot have the same car)   
if numel(intersect(ID1,ID2))
continue
end
            INCREASE2{jj,jj2}=max(HH2+V11+V22)./max(HH2);
           %IDcell2{jj,jj2}=[ID1 ID2];
        end
end
