关与数据传递求助
本人刚接触matlab,遇到了些问题,请各位大侠帮忙我在一个按钮的callback那里需要调用一个另外已经编好的程序,但是我不知道怎么把界面上输入的数据,使用到那个程序里.... 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.

S.ls = uicontrol('style','list',...
'unit','pix',...

'callback',{@pb_call,S});
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.
