Unable to export recorded audio as wav file

I got the code for virtual piano from https://www.mathworks.com/matlabcentral/fileexchange/21262-matlab-piano. but the output function is not working . please help.

% --- Executes on button press in OutToWav.

function OutToWav_Callback(hObject, eventdata, handles)

% hObject handle to OutToWav (see GCBO)

% eventdata reserved - to be defined in a future version of MATLAB

% handles structure with handles and user data (see GUIDATA)

SoundVector = handles.SoundVector;

SampleRate = handles.SampleRate;

if SoundVector == 0

return;

else

Filename = get(handles.Filename, 'String');

wavwrite(SoundVector, 1/SampleRate, 32, Filename);

end
