control properties of app designer components from a Matlab function block of a Simulink model

Hi,

I would like to control the properties of some app designer components using a Matlab function block of my Simulink model. Is that possible? In case yes, could you provide how can I do it?

Thanks in advance for your comments.

Regards,

Mauricio

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!
