How can i exchange values between 2 functions (2 different buttons on a GUI) ?

By pressing first button I calculate some matrices. By pressing another button, I would like to save the previous values into a file. I do not know how to exchange the values between 2 function.

First function is:

function pushbutton1_Callback(hObject, eventdata, handles)

Second function is:

function pushbutton8_Callback(hObject, eventdata, handles)

I have tried to insert output argument on first function but it doesn't work or maybe I have just managed it in a wrong way.

Thanks to who wanna help me.
