matlab串口通信和GUI学习

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