Hi there,

I have a for loop below which calls the same function "Optimiseenergy" in each iteration. There are 2 outputs from this function "Energyin" and"Energyout". Could anybody suggest how I can prevent the outputs from being overwritten in each iteration? Ideally I would like to save the outputs as Energyin1, Energyout1, Energyin2, Energyout2... etc

I tried changing the function call to this but it doesn't work.

[Energyin(i),Energyout(i)] = Optimiseenergy(at(i),dt(i+1),SOC(i),20);

Thank you

JN = 3; %
dt=[11  29 38]; % departure times
at=[14 33 42]; % arrival home times 
SOC(1)=SOC0;
for i=1:1
     SOC(i) = SOC0 - (at(i)-dt(i))*1.22;
     [Energyin,Energyout] = Optimiseenergy(at(i),dt(i+1),SOC(i),20);
end
for i=2:JN-1
     SOC(i) = 20 - (at(i)-dt(i))*1.22;
     [Energyin,Energyout] = Optimiseenergy(at(i),dt(i+1),SOC(i),20);
end

Hi!

Use arrays to save the results:

% allocate arrays for results
Energyin = zeros(JN-1, 1);
Energyout= zeros(JN-1, 1);
for i=2:JN-1
       SOC(i) = 20 - (at(i)-dt(i))*1.22;
       % save results
       [a, b] = Optimiseenergy(at(i),dt(i+1),SOC(i),20);
  Energyin(i) = a;
Energyout(i) = b;
  end

Then, store them in a cell array.

% allocate arrays for results as matrix
Energyin = cell(JN-1, 1);
Energyout= cell(JN-1, 1);
for i=2:JN-1
    SOC(i) = 20 - (at(i)-dt(i))*1.22;
    % save results
    [a, b] = Optimiseenergy(at(i),dt(i+1),SOC(i),20);
    Energyin{i} = a;
    Energyout{i} = b;
  end
