Hi guys, I have two functions:

1) function sol = CreateRandModel(model)

2) function qnew = CreateNeighbor(q,model)

as an output of my first function I get a structure sol where:

sol = 
struct with fields:
sum_fburn_rand: 1.2503e+06
fburn_rand: [1×25 double]
arrival_time: [1×25 double]

In the second function I'm only intersted in the field sum_fburn_rand from the output of my first function, I would like to generate in a loop an array of 10 different values based on how this value is generated in the first function. Could you help me with code?

CreateNeighbor()
ans = 1×10
    0.3231    0.6672    0.5264    0.2974    0.2440    0.9573    0.2416    0.2394    0.1875    0.8790
function sol = CreateRandomModel()
sol = struct( ...
    'sum_fburn_rand',rand(), ...
    'fburn_rand',rand(1,25), ...
    'arrival_time',rand(1,25));
end
function result = CreateNeighbor()
result = zeros(1,10);
for ii = 1:numel(result)
    temp = CreateRandomModel();
    result(ii) = temp.sum_fburn_rand;
    % or, without the temporary variable 'temp':
    result(ii) = getfield(CreateRandomModel(),'sum_fburn_rand');
end
end
