I have created a demo App using AppDesigner and a demo model in Simulink whose block parameters I am updating from the App itself. Here is the Code View of App->
methods (Access = private)
% Code that executes after component creation
function init(app)
app.a = 5;
end
% Button pushed function: LaunchModelButton
function launchModel(app, event)
launchModel(app.a);
end
% Value changed function: Gain_ParamEditField
function update_prop_a(app, event)
value = app.Gain_ParamEditField.Value;
app.a = value;
end
end
Here is the MATLAB script ‘launchModel’->
function launchModel(a)
k = int2str(a);
open_system('demoModel1');
set_param('demoModel1/Gain','Gain',k);
open_system('demoModel1/Scope');
sim('demoModel1');
end
Here is the model 'demoModel1'->
