Starting in R2017b, App Designer supports input arguments for apps. To add input arguments to an app, open the app in App Designer and click Code View. Then click App Input Arguments in the Editor tab.

Refer to the following documentation for more details: https://www.mathworks.com/help/matlab/creating_guis/app-designer-startup-function.html

If you use R2017a or prior releases, try the following workaround:

Create a public function in your app (use the "+ Function" in Code View and choose the "public" option) and use that to pass in any "input variables" after the app is created.

For example:

hApp = myapp;
MySetupFunction(hApp, input1, input2);
