Publisher description for MATLAB Huffman

MATLAB Huffman program icon

[CODE,COMPRESSION]=HUFFMAN5(P) P is the probability (or number of occurences) of each alphabet symbol CODE gives the Huffman code in a string format of ones and zeros COMPRESSION gives the compression rate Huffman5 works by first building up a binary tree (eg p =[ .5 .2 .15 .15]) Such that the tree always terminates at an alphabet symbol and the symbols furthest away from the root have the lowest probability. The branches at each level are labeled 0 and 1. For this example CODE would be 1 00 010 011 and the compression rate 1.1111
