从按钮组中的单选按钮检索值并导出到工作区

Question

我正在尝试修改此 gui http://www.mathworks.com/matlabcentral/fileexchange/20604-3d-slice-viewer 因为我想添加一项功能。这个新功能是评估疾病，我的意思是如果当前在查看器上的切片有疾病，用户点击是，否则点击否。每个病人应该做几次。出于此学习目的，我使用来自 matlab 的 mri 数据。

问题是我使用指南添加了一个带有两个单选按钮的新框（按钮组）。但我无法从 gui 中获得任何价值。当我只使用 get(eventdata.NewValue, 'Tag') 时，每次单击按钮时，我都可以在命令中看到 window 按钮的值，但我不知道如何保存这些点击。我尝试了以下但没有成功：

% --- Executes when selected object is changed in Assess.
function Assess_SelectionChangeFcn(hObject, eventdata, handles)
% hObject    handle to the selected object in EmphyAssess 
% eventdata  structure with the following fields (see UIBUTTONGROUP)
%   EventName: string 'SelectionChanged' (read only)
%   OldValue: handle of the previously selected object or empty if none was selected
%   NewValue: handle of the currently selected object
% handles    structure with handles and user data (see GUIDATA)

switch get(eventdata.NewValue,'Tag')   % Get Tag of selected object
    case '1'
        value = 1; 
        Setappdata(hObject,'result', value); 

      case '2'
          value= 0; 
          Setappdata(hObject,'result', value); 

end

% --- Outputs from this function are returned to the command line.
function varargout = SliceBrowserIsa_OutputFcn(hObject, eventdata, handles)
% varargout  cell array for returning output args (see VARARGOUT);
% hObject    handle to figure
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)

% Get default command line output from handles structure

   varargout{1} = getappdata(hObject,'result');

Answer 1

您可以使用 guidata(hObject,handles) - look here for more info 更新句柄对象。之后您应该可以访问该值。

您的问题还提到导出到工作区 - 您可以使用 assignin('base', 'variable', value) - see here
