How to create a variables in simulink of a pre-set variables within a Simulink.SimulationInput

It is my understanding that you want to create an additional variable in Simulink using the "setVariable" function. However, to use the value of ‘X’ for setting ‘Y’, you need to first get the value of ‘X’.

You can follow the below workaround to set the value of ‘Y’,

for i=1:iterations
     %LOAD SYSTEM 
     in(i)=Simulink.SimulationInput('MDL');
     X_value = 1000; % Set X value 
     in(i) = in(i).setVariable('X', X_value,'Workspace','MDL');
     
     % Create an additional variable Y
      Y_value = X_value * 10; % Use the X value for setting Y
      in(i) = in(i).setVariable('Y', Y_value,'Workspace','MDL'); 
end

You can also use “getVariable” function to fetch the value of ‘X’ and assign it to ‘Y’. “getVariable” function returns a value of variable in the model workspace of a model.

Refer to the following documentation to know more about “getVariable” function”:

Return value of variable in the model workspace of a model - MATLAB getVariable - MathWorks India

Hope this helps!
