Webcode = huffmanenco(sig,dict) encodes input signal sig using the Huffman codes described by input code dictionary dict. sig can have the form of a vector, cell array, or alphanumeric cell array. If sig is a cell array, it must be either a row or a column.dict is an N-by-2 cell array, where N is the number of distinct possible symbols to encode. We have explored Huffman Encoding which is a greedy algorithm that encodes a message into binary form efficiently in terms of space. It is one of the most successful Encoding Algorithms. We have present a step by step example of Huffman Encoding along with C++ implementation. Meer weergeven First of all, let us understand What is "Encoding"?
