How to save a callback function
显示 更早的评论
I need to save a datacursormode callback function, as a local variable (at least the syntax) . The argument of this function is my object
I am updating an object and then passing the saved function and the updated object in my datacusrormode UpdateFcn.
How to do it ? I tried the func2str and str2func without success.

It would help if you showed some relevant part of code for your problem as I'm not really sure I understand what it is you are wanting to do. You can save a callback as a function handle simply by doing something like this:
f = @myCallbackFcn;
where myCallbackFcn is defined somewhere as:
function myCallbackFcn( ~, eventObj )
...
end
You can also use an anonymous function if you wish to pass in more arguments than the default mandatory ones for that callback.
