Hi,

I have many signals in my simulink modell, that I want to convert into a structure. So I use a matlab function block, that looks like this:

function mystruct = create_struct( u )

   mystruct.a = u(1);
   mystruct.b = u(2);

end

Then I want to use this "struct-output" as input for another function. But this seems not to work. Have you any idea how to solve this? Thanks

In Simulink structured data is represented as Simulink.Bus objects to create a Simulink Bus you can do this by typing in your workspace

varname = Simulink.Bus

After creating a bus in your Simulink model use this bus object as your datatype for your Simulink block port.
