the handle to %the existing singleton*.%%JISUANQI1('CALLBACK',hObject,eventData,handles,...)calls the local %function named CALLBACK in JISUANQI1.M with the given input arguments.%%JISUANQI1('Property','Value',...)creates a new JISUANQI1or raises the %existing singleton*.Starting from the left,property value pairs are %applied to the GUI before jisuanqi1_OpeningFunction gets called.An %unrecognized property name or invalid value makes property application %stop.All inputs are passed to jisuanqi1_OpeningFcn via varargin.%%*See GUI Options on
