我正在尝试使用GUIDE创建一个GUI，它允许用户选择两个按钮中的一个。按钮中的字符串每次都会变化（我还没有自动化），但是当按下任何按钮时，我希望GUI将字符串作为输出变量。
我有代码来显示工作区中的输出，但是在调用OutputFn之前删除了句柄。有关如何解决此问题的任何建议吗？
另外，我想使用＆＃39; Next＆＃39;按钮。理想情况下，这应该以一种迭代的方式拉出按钮上显示的下两个文本，但我现在很乐意超越获取输出的障碍。这就是我到目前为止所拥有的： / p>
function varargout = Select_A_B(varargin)
% SELECT_A_B MATLAB code for Select_A_B.fig
% SELECT_A_B, by itself, creates a new SELECT_A_B or raises the existing
% singleton*.
%
% H = SELECT_A_B returns the handle to a new SELECT_A_B or the handle to
% the existing singleton*.
%
% SELECT_A_B('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in SELECT_A_B.M with the given input arguments.
%
% SELECT_A_B('Property','Value',...) creates a new SELECT_A_B or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before Select_A_B_OpeningFcn gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to Select_A_B_OpeningFcn via varargin.
%
% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one
% instance to run (singleton)".
