Hi,
From my understanding you want to control the components of an app from Simulink function block.
1.Create a function and add the code for modifying the required components properties. For example
function output = func1(input)
coder.extrinsic('func1') %add this line to bypass code generation and to not get the same message as error
if isempty(app) || ~isvalid(app)
app = app1; % create an instance of app
end
app.MessageEditField.Value = "Hello from Simulink!"; % Modify the properties
2. Call this function from the MATLAB function block of your Simulink model.
function y = fcn(u)
coder.extrinsic('func1')
y = func1(u);
Hope this helps!
