【求助】为什么guide编写的程序只能运行一次？

下面的程序是用来输出黑体辐射亮度波形的。 需要输入黑体色温和波长范围。

不知道为什么guide编写的程序只能运行一次。 第二次输入新的色温和波长范围后出现错误：

Invalid handle object

程序如下：

function varargout = simpleguii(varargin)

% SIMPLEGUII M-file for simpleguii.fig

% SIMPLEGUII, by itself, creates a new SIMPLEGUII or raises the existing

% singleton*.

%

% H = SIMPLEGUII returns the handle to a new SIMPLEGUII or the handle to

% the existing singleton*.

%

% SIMPLEGUII('CALLBACK',hObject,eventData,handles,...) calls the local

% function named CALLBACK in SIMPLEGUII.M with the given input arguments.

%

% SIMPLEGUII('Property','Value',...) creates a new SIMPLEGUII or raises the

% existing singleton*. Starting from the left, property value pairs are

% applied to the GUI before simpleguii_OpeningFunction gets called. An

% unrecognized property name or invalid value makes property application

% stop. All inputs are passed to simpleguii_OpeningFcn via varargin.

%

% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one

% instance to run (singleton)".

%
