How to remove the last row in a matrix?

Using GUIDE, I have made a table. In that, there is a "pushbutton" if the user wants to remove the rows.

I am not able to remove

% --- Executes on button press in remove_button.

function remove_button_Callback(hObject, eventdata, handles)
% hObject    handle to remove_button (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)

% By default the remove button will only remove the last row in the 
% table

dat = get(handles.eptable,'Data');
sz = size(dat);
dat(sz(1),1)=[];

I get the following error:

??? A null assignment can have only one non-colon index.

What is the solution of removing the last row?

dat(sz(1),:) = [];

or

dat(end,:) = [];

Perfect!

Need to revise the basics again.

Thanks.

@Walter: a small follow up question:

The user with the push button, REMOVE can delete all the ROWS.

I want to make sure that atleast 1 row remains. How will that condition be inserted ?

Thanks.

if size(dat,1) > 1; dat(end,:) = []; end

dat = dat(max(1,size(dat,1)-1),:)

Thanks Walter and Jos for the feedback!
