Hi guys.
I have designed an app in app designer and it calls a .m file that contains a function.
In that function I do some works and at the end I want to change in some parameters. For example I want to disable a button in app. Could any one help me about it?

@SRii - you could have the function return a parameter that indicates that the button should be disabled (doesn't have to explicitly say "disable button" but perhaps a status that your GUI would interpret as a reason to disable the button).

Thanks for your reply.
Actually I am working with serial ports and I wrote a function that is been called when a data is received. so there's no where to check the return value

pass the app to the function. Use the app to extract the handle of the button. Set the button property to disable.
