一个简单的matlab图形界面程序GUI

function varargout = showGUI(varargin)
% SHOWGUI MATLAB code for showGUI.fig
% SHOWGUI, by itself, creates a new SHOWGUI or raises the existing
% singleton*.
%
% H = SHOWGUI returns the handle to a new SHOWGUI or the handle to
% the existing singleton*.
%
% SHOWGUI('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in SHOWGUI.M with the given input arguments.
%
% SHOWGUI('Property','Value',...) creates a new SHOWGUI or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before showGUI_OpeningFcn gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to showGUI_OpeningFcn via varargin.
%
% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one
% instance to run (singleton)".
