recursively transverse a strut in matlab

To recursively traverse a struct in MATLAB, we can write a function that takes the struct as an input argument and then iterates over its fields using a loop. If a field is itself a struct, we call the function recursively on that field. Here's an example function that prints out the names of all fields in the struct, including any nested structs:

main.m
function traverseStruct(s)
    % Iterate over struct fields
    fields = fieldnames(s);
    for i = 1:numel(fields)
        field = fields{i};
        % Print field name
        disp(field);
        % Recursively traverse sub-structs
        if isstruct(s.(field))
            traverseStruct(s.(field));
        end
    end
end

We can call this function with a sample struct like this:

main.m
% Define a sample struct
s.a = 1;
s.b = 2;
s.c.d = 3;
s.c.e.f = 4;

% Traverse the struct recursively
traverseStruct(s);

This will produce the following output:

main.m
a
b
c
d
e
f

Note that in this example, the disp function is used to print out the names of the fields. Depending on what you want to do with the struct, you can modify the function to perform other operations on the fields instead.
