Calling a functions fieldname without saying its name.

Hi there,

I have a structure called 'AerodynamicData.Cx.ActuatorName' where x is a wildcard character and ActuatorName is a wildcard phrase.

For example, I have structure called 'AerodynamicData'. This structure has two fields called Cm and Cp. Inside Cm there are two fields. Inside Cp there is one field.

 AerodynamicData.Cm.BodyFlap
 AerodynamicData.Cm.Speedbrake 
 AerodynamicData.Cp.Aileron

Possible structures^^

Now my question is how do I loop through all the structures that have this naming convention >> 'AerodynamicData.Cx.ActuatorName'

You can use the function fieldnames and a for loop

%s = somestruct
f1 = fieldnames(s)
for i = 1:length(f1)
    fn1 = f1{i};
    s2 = s.(fn1);
    f2 = fieldnames(s2)
    for j = 1:length(f2)
        fn2 = f2{j};
        value = s2.(fn2);
        % do something with the value
    end
end
