香农—费诺编码的MATLAB实现，程序已在，可直接运行-Shannon- Fenno encoded MATLAB realization of the process had been in the direct operation

和Huffman-Tree一样，Shannon-Fano coding也是用一棵二叉树对字符进行编码。但在实际操作中呢，Shannon-Fano却没有大用处，这是由于它与Huffman coding相比，编码效率较低的结果（或者说香农-范诺算法的编码平均码字较大）。-And Huffman-Tree, like, Shannon-Fano coding is using a binary character coding. However, in practice it, Shannon-Fan
