Pass variable from one callback to another

Hey guys, I wanted to know how to pass the value of a variable from one callback function to another withing the same GUI. Thanks.

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.

Now I am clear. Thanq
