Matlab GUI using getappdata and setappdata

Basically what I want to do is have one gui that is just a t开发者_C百科itle and a push button that calls uigetfile(), and once the user selects an image, the gui closes, and opens a new gui that contains the image, functions applied to the image, and information about the image. I have made all the code for everything, I just can't figure out how to use setappdata and getappdata so that the new gui opens with everything I want.

Mathworks website contains detailed information for most of matlabs functions.
