1.MATLAB界面编程 .m文件生成.exe文件相关问题及解答

MATLAB gui 界面设计过程中遇到的问题及解决方法

MATLAB版本r2014a

1.滑块的回调函数如下，功能：得到K的值，并将K值显示到静态文本中（K值为整数）

function slider_val_Callback(hObject, eventdata, handles)
% hObject    handle to slider_val (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,'Value') returns position of slider
%        get(hObject,'Min') and get(hObject,'Max') to determine range of slider
val=get(hObject,'Value');
if rem(val,1)~=0
    set(handles.txt_display,'String',num2str(round(val)));
end
global K;
K=round(val);
