我正在制作一个程序，记录用户按下按钮以响应一系列音调。我将按钮按下的时间存储在矢量（pushTimes）中，我将其存储在GUIDE的“句柄”结构中，我希望按下每个按钮的新时间附加到pushTimes矢量。但是，句柄似乎没有存储带有附加值的新向量，在按下按钮后我留下了一个空向量。
编辑：因为人们很难再现错误，我发布整个文件相关代码在callBack pushButton1中。 pushButton2和pushButton3分别是“暂停”和“开始”按钮。即使我没有暂停程序，也会发生错误。
function varargout = simpleGui(varargin)
% SIMPLEGUI M-file for simpleGui.fig
% SIMPLEGUI, by itself, creates a new SIMPLEGUI or raises the existing
% singleton*.
%
% H = SIMPLEGUI returns the handle to a new SIMPLEGUI or the handle to
% the existing singleton*.
%
% SIMPLEGUI('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in SIMPLEGUI.M with the given input arguments.
%
% SIMPLEGUI('Property','Value',...) creates a new SIMPLEGUI or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before simpleGui_OpeningFcn gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to simpleGui_OpeningFcn via varargin.

% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one
% instance to run (singleton)".
