这是使用Matlab实现的Huffman编码与绘图的程序。编码过程比较简单，是通过建立Huffman树，再进行简单的遍历得到。 主要贡献在绘图部分。这是迄今为止唯一一个画出Huffman生成树的Matlab程序。-This is a piece of Huffman coding and graphics program based on matlab. The encoding process is relatively simple, through the establishment of Huffman tree, then the simple traversal get. The main contribution is the drawing section. This is by far the only piece of Matlab code to draw Huffman tree.
