??? Error: File: E:\matlabb\work\js.m Line: 107 Column: 1 Illegal use of reserved keyword "function

% --- Executes just before js is made visible.
function js_OpeningFcn(hObject, eventdata, handles, varargin)
% This function has no output args, see OutputFcn.
% hObject handle to figure
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)
% varargin command line arguments to js (see VARARGIN)

% Choose default command line output for js
handles.output = hObject;

% Update handles structure
guidata(hObject, handles);

% UIWAIT makes js wait for user response (see UIRESUME)
% uiwait(handles.figure1);

% --- Outputs from this function are returned to the command line.

% varargout cell array for returning output args (see VARARGOUT);

% Get default command line output from handles structure

end

function edit1_Callback(hObject, eventdata, handles)
% hObject handle to edit1 (see GCBO)
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)

% Hints: get(hObject,'String') returns contents of edit1 as text

input=Str2num(get(hObject,'String'));
if(isempty(input))
Set(hObject,'string','0')
emd
guidata(hObject,handles);

% --- Executes during object creation, after setting all properties.
function edit2_CreateFcn(hObject, eventdata, handles)

Answer 1

if(isempty(input))
Set(hObject,'string','0')
emd %应该为end
