方法很多,内嵌函数,setappdata,handles等
一个简单的小例子,希望对你有用- function [] = GUI_1()
- % Demonstrate how to delete an entry from a uicontrol string.
- % Creates a listbox with some strings in it and a pushbutton. When user
- % pushes the pushbutton, the selected entry in the listbox will be deleted.
- %
- % Suggested exercise: Modify the GUI so when the user deletes a certain
- % string, the 'value' property is set to the previous string instead of to
- % the first string.

- function [] = pb_call(varargin)
- % Callback for pushbutton, deletes one line from listbox.
- S = varargin{3}; % Get the structure.
- L = get(S.ls,{'string','value'}); % Get the users choice.
- % We need to make sure we don't try to assign an empty string.
- if ~isempty(L{1})
- L{1}(L{2}(:)) = []; % Delete the selected strings.
- set(S.ls,'string',L{1},'val',1) % Set the new string.
