Structure as property in app designer

How can I define a structure as property in app designer? And how can I save this struct as a .mat file?

[Mohammad Sami]

You can create a property in you app designer by clicking Property and then public or private.

You can assign a struct to this property in either a startup function or in any other callbacks.

You can save this property in a callback assigning the value of the property to any variable and then saving that variable to file as per normal.

Can you provide a code snippet of how to do this?

You can initialise the property as struct in properties block. You don't type this wherever, there's a button on the toolbar to create a property block.

properties (Access = public)
    Property = struct() % Description
end
