What a callback function means? Access to hyperlinks of structure figures fields. Workspaces. disp(ans).

NOTE: THE CODE BELOW IS THE SAME OF MY PAST QUESTION.

Hello and greetings to all !!!

My goal is, what does a callback function mean? Also, through this, to try to do in another way in based on what the following code does. In other words, if the callback works for doing something what the code below does. Something like the things mentioned in the title of the question.

In one of my previous questions I putted "callback" as a tag and in the link there are several examples. But, I need a more explicit and simple example to carefully, tha is, slowly, understand what it means.

Whether it works or not, I would like to know what a callback is. Please

Thanks in advance.

This question doesn't clarify your previous one. Please respond in a comment there instead of posting a new question.

Never mind

Maybe in another chance. I'm a little sleepy.

So long. Bye

Thanks anyway !!!
