This file contains some MatLab m-files (version 5.2) 
which do complete Huffman Coding.
The files are:
hufflen  
  Based on probability (or number of occurences) of each symbol 
  the length for the Huffman codewords are calculated.
  HL = hufflen(S);
huffcode
  Based on the codeword lengths this function find the Huffman codewords
  HK = huffcode(HL);
hufftree
  make the Huffman-tree from the length of Huffman codes
  Htree = hufftree(HL);
huff03
  Huffman encoder/decoder, one or two vectors of non-negative
  integers are Huffman coded.
  y = huff03(x1, x2);     % encoding
  [x1, x2] = huff03(y);   % decoding
