MATLAB: Using Structures

MATLABsimulinkstructures

I'm new to Simulink and I'm hoping there is an easy answer I am just missing it. I've been looking on forums and everywhere I can think of for weeks, but without success. Is there a way to pass complex, dynamic structures in Simulink without having to create a bus that matches the structure? Maybe a different way to put it is, how can I use MATLAB or C+ objects in Simulink?

Thanks Kaustubha,

That is what I thought the answer was but I was hoping otherwise.

You could have the following structure:

s.myfield = 10;
s.another = 20;
s.hello   = 30;

Now suppose you have a list with the fieldnames which also happens to be the function to retrieve them from a structure:

fnames = {'myfield','another','hello'};

(Note that I didn't call the list with the name of the function)

Now you can manipulate the structure using dynamic fieldname indexing:

for n = 1:numel(fnames)
    tmp = s.(fnames{n});
    % do stuff with tmp or directly with s.(fnames{n}) 
end

This is a complete reference to manipulate structures: structures

You mean like this?

temp_Q=1:20;
temp_q=struct('ff',mat2cell(temp_Q,1,repmat(1,20,1)))
