Use a shared variable, or store the data in your handles structure via guidata(), or use setappdata(), or store the data in the UserData field of some object, or use a persistent variable, or use a global variable.
You can take any of these approaches.
In the place you need to use the data, retrieve it from where-ever you stored it.
