can you be more specific ?

[Walter Roberson]

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.
