The question is very basic. I recommend to read the Getting Started chapter in the documentation.
To find corresponding locations in the documentation:
docsearch DeleteFcn

@Ram: It is still not getting clearer. You want to know the difference between these functions and what?
"Callback function" means, that the function is called, when an event is triggered. E.g. the three above shown properties of the FIGURE object contain pointers to the corresponding callback functions. E.g. button have callback functions also, which are called, if the button is clicked with the left ('Callback' property) or other mouse keys ('ButtonDownFcn' property).
