Using assignin command assign that to base workspace and fetch the same using evalin at another callback.
Else use nested function ex: func1(func2(x))

@Vivek: No, don't do this. Poluting the base workspace is a really bad idea.

Why, what's wrong with putting a variable in the workspace? Why is that "polluting"?

This topic has been discussed very frequently, such that searching will be useful:

You will find many suggestions concerning the commands setappdata and guidata, which both store the variables locally in the GUI.
