2.5 寻求码生成多项式
三、部分源代码
function varargout = co_decode(varargin)
% CO_DECODE M-file for co_decode.fig
% CO_DECODE, by itself, creates a new CO_DECODE or raises the existing
% singleton*.
%
% H = CO_DECODE returns the handle to a new CO_DECODE or the handle to
% the existing singleton*.
%
% CO_DECODE('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in CO_DECODE.M with the given input arguments.
%
% CO_DECODE('Property','Value',...) creates a new CO_DECODE or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before co_decode_OpeningFcn gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to co_decode_OpeningFcn via varargin.
%
% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one
% instance to run (singleton)".
%
% See also: GUIDE, GUIDATA, GUIHANDLES
