I have an Array of 5 structures, say A(1), A(2)...A(5). Each of them have 3 fields which are: A(i).field1, A(i).field2, A(i).field3.
I would like to assign a constant value to each field in all structure using Simulink blocks. I am using for loop to circle amongst A(i). How can I access field1, field2, field3 in each structure?

You can use MATLAB Function as following.
I attached example model and .mat included struct data.

Thank you! Is it impossible to create a structure without a .mat file?

@VuKhoa,
You need a .mat file.
If you can use the bus signal, you can use a method like the attachment.
The method is to assign structure variables to bus signals.
run myData
run myBus
open_system('BusModel');
sim('BusModel');
