编辑框文本传输问题
本人碰到如下问题：编辑文本框时数据怎么才能传送到我自己的程序里面去，在论坛里面看了一些帖子，也照着一些朋友提供的方法试过，但是行不通，出现如下错误提示：
??? Undefined variable "data" or class "data.Ix".
Error in ==> gui_lsq>pushbutton1_Callback at 425
B1=E+a1*sin(data.Ix)+a1*a1*(1-cos(data.Ix));
Error in ==> gui_mainfcn at 75
feval(varargin{:});
Error in ==> gui_lsq at 45
gui_mainfcn(gui_State, varargin{:});
??? Error while evaluating uicontrol Callback.
在Ix的回调函数下，我用的代码是：
function edit18_Callback(hObject, eventdata, handles)
% hObject handle to edit18 (see GCBO)
% eventdatareserved - 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 edit18 as text
% str2double(get(hObject,'String')) returns contents of edit18 as a double
user_string=get(hObject,'String');
user_entry= str2double(get(hObject,'String'));
if isnan(user_entry)
errodlg('You must entry a number value','Bad Input','model')
% else Ix=user_entry*pi/180;
end
data=getappdata(gcbf,'metricdata');
data.Ix=user_entry;
setappdata(gcbf,'metricdata',data);
而在我进行运算的主程序里，我用的代码是：
function pushbutton1_Callback(hObject, eventdata, handles)
% hObject handle to pushbutton1 (see GCBO)
% eventdatareserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)
button_state=get(hObject,'Value')
if button_state==get(hObject,'Max')
syms u t b wt wp O xm ym zm
ww=1;
w=6.33912;
c=ww*t;
f=w*t;
%旋转刀倾角
aa1=15*pi/180;
a1=;
E=;
B1=E+a1*sin(data.Ix)+a1*a1*(1-cos(data.Ix));
各位只要看到data.Ix的定义及使用这一段就可以了。。我是新手，对于这种情况实在是不会分析，只能试，现在试不出来，只能上这儿来向各位高手求助了。。请大家帮忙分析一下是什么原因！！
怎样将可编辑文本框的输入内容传递到我自己的运算程序里面去。。谢谢！ 19372612
这是我的qq，如果方便，请q我，多多指教！！！
