How can I put a struct output into the i-th field of a struct on MATLAB?

I have a for loop that runs a simulation 100 times. The results of that simulation go into a struct. For simulation run I have out.S, out.I, out.R and I want to then store the results of each simulation within another struct or array so I can then work out the average output across the 100 simulations.

Anyone any ideas of how to store the output from a for loop using structs? I usually use arrays but this one requires structs.

Use dot indexing to create a struct() , see https://www.mathworks.com/matlabcentral/answers/321489-how-can-i-create-a-structure-with-a-loop#answer_251562

for ...
S.result(i)... % S is your struct
end

Hi,

You can do it as follows:

After that you have out.S as an array so you can assign it to any other struct.

for i =1:NumberOfSimulations
    out.S(i) = simResult1;
    out.I(i) = simResult2;
    out.R(i) = simResult3;
end

or you can do below:

Your outputs will be different struct arrays.

for i = 1:NumberOfSimulations
    S.result(i) = out.S;
    I.result(i) = out.I;
    R.result(i) = out.R;
end
