Huffman and Shannon-Fano source coding

对通信中的信源的二进制编码的实现，有香农编码，费诺编码以及霍夫曼编码-Source of communication in the realization of the binary code, there is the Shannon coding, coding, and Huffman coding Fenno

This technique doesn t involve sorting of probabilities as in Shannon-Fano coding. The following formula is used to calculate F (x) which in turn generates the code F (x) = F(x) + p(x) / 2, where F(x) is cummulative sum of probabilities p(x).

matlab files that generate Huffman code, Shannon code,LZW code and Fano code. The myfile.txt is a arbitrary text file that will be coded.
