my_huffman.m

对输入的字符串各个字符出现次数的概率进行霍夫曼编码

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