基于MATLAB的工件参数检测系统设计与实现

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