Accessing a variable used in a botton from another button

Hi , I am using matlab R2013a

I declared a variable name as wav in a button's callback function as shown below

function record_Callback(hObject, eventdata, handles)

wav=wavrecord(10*8000,8000);

Now, I want to access this variable from the callback function of another button as shown below

function play_Callback(hObject, eventdata, handles) sound(wav);

Any easy way to do it?

This topic is dicussed frequently and you can find it e.g. by searching in this forum for "share variable between callbacks". See e.g. http://www.mathworks.com/matlabcentral/answers/146260-how-to-share-variables-between-two-gui-callbacks

function record_Callback(hObject, eventdata, handles)
handles = guidata(hObject);
handles.wav = wavrecord(10*8000,8000);
guidata(hObject, handles);

function play_Callback(hObject, eventdata, handles)
handles = guidata(hObject);
sound(handles.wav);
