MATLAB: How to change a variable inside a Value structure in a Simulink.Parameter


I have a Simulink.Parameter object P where P.Value is a struct, so how can I change a variable inside the Value structure?

You can do this by using the normal MATLAB assignment syntax as in the following example:
Construct a Simulink.Paramter object P with some dummy data in P.Value and display it in the Command Window:
>> P = Simulink.Parameter;
>> P.Value = struct('field1',1,'field2',2)
>> P.Value
Next change the value in P.Value.field1 from 2 to 3 using the usual assignment syntax and display it in the Command Window:
>> P.Value.field1 = 3;
>> P.Value
