主函數 C2M
  1 function varargout = C2M(varargin)
  2 val = zeros(1,1);
  3 
  4 % C2M MATLAB code for C2M.fig
  5 %      C2M, by itself, creates a new C2M or raises the existing
  6 %      singleton*.
  7 %
  8 %      H = C2M returns the handle to a new C2M or the handle to
  9 %      the existing singleton*.
 10 %
 11 %      C2M('CALLBACK',hObject,eventData,handles,...) calls the local
 12 %      function named CALLBACK in C2M.M with the given input arguments.
 13 %
 14 %      C2M('Property','Value',...) creates a new C2M or raises the
 15 %      existing singleton*.  Starting from the left, property value pairs are
 16 %      applied to the GUI before C2M_OpeningFcn gets called.  An
 17 %      unrecognized property name or invalid value makes property application
 18 %      stop.  All inputs are passed to C2M_OpeningFcn via varargin.

 20 %      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
 21 %      instance to run (singleton)".
