Matlab GUI：如何存储按钮的顺序和结果
Matlab GUI: How to store the order and results of a push buttons
我有一个带有 2 个按钮的简单 GUI，一个说是，另一个说不是。
如何记录每个按钮被按下的次数，更重要的是顺序？
谢谢。
要计算 "Yes" 和 "No" 的数量，您可以在 GUI 中定义：
- "Yes"
的计数器
- "No"
的计数器
为了跟踪您可能定义的 "Yes" 和 "No" 的顺序
- "global" 计数器用于 "Yes" 和 "No"
- 一个数组，其中根据已按下的按钮顺序存储 "Yes" 例如“1”和 "No" 作为“-1”
- 根据按下的按钮
顺序存储的字符串"Yes""No"
所有上面定义的变量都可以在 GUI OpeningFcn 中初始化，然后存储在 GUI data 的结构中（通过使用 guidata 函数。
那么变量是：
- 设置在"Yes"和"No"
pushbutton callback
- 存储在
GUI data的结构中（再次用guidata函数
在 "Yes" 和 "No" pushbutton callback 中，您还可以打印 "Yes" 和 "No" 按钮被按下的次数及其序列分为两个 text box.
您还可以使用将 "Yes" / "No" 存储为 1 和 -1 的数组来绘制图形等。
下面使用GUI的编码yes_no_counter来测试解决方案；在 GUI 中：
- "Yes"
pushbutton tag= `yes_btn
- "No"
pushbutton tag= no_btn
- 第一
text box tag="text1"
- 秒
text box tag="text2"
yes_no_counter.m
function varargout = yes_no_counter(varargin)
% YES_NO_COUNTER MATLAB code for yes_no_counter.fig
% YES_NO_COUNTER, by itself, creates a new YES_NO_COUNTER or raises the existing
% singleton*.
%
% H = YES_NO_COUNTER returns the handle to a new YES_NO_COUNTER or the handle to
% the existing singleton*.
%
% YES_NO_COUNTER('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in YES_NO_COUNTER.M with the given input arguments.
%
% YES_NO_COUNTER('Property','Value',...) creates a new YES_NO_COUNTER or raises the
