I want to load my dataset or access any other variables that are saved to my matlab folder or are in my workspace currently from the matlab GUI I created. But when I call my functions on callback function of a button, I can't do it. Could you give me a simple example how to do it?

"any other variables that are saved to my matlab folder"   do you mean saved in a mat-file in the current folder?
See evalin

filename = 'durer.mat';
myVars = {'X','caption'};
S = load(filename,myVars{:})
to the callback function.
 
" or are in my workspace"   see evalin, Execute MATLAB expression in specified workspace and add
my_variable = evalin( 'base', 'my_variable' )
to the callback function.

"I can't do anything on it"
- I assume that assignin actually assigned a variable in the base workspace
- load assigns a value to the variable S.  dataset2 is not a variable, but a field of the struct S. Try churn = S.dataset2.churn;.
Comments
- Do a few excercises with Access Data in a Structure Array
- Don't make it a habbit to use globals.
