Description: Huffman 这个名字，程序员们至少会联想到二叉树和二进制编码。的确，我们总以 Huffman 编码来概括 D.A.Huffman 个人对计算机领域特别是数据压缩领域的杰出贡献。我们知道，压缩 = 模型 + 编码，作为一种压缩方法，我们必须全面考虑其模型和编码两个模块的功效；但同时，模型和编码两个模块又相互具有独立性。-Huffman, programmers will at least think of a binary tree and binary coding. Indeed, we always Huffman coding to summarize D. A. Huffman personal computer areas, especially in the field of data compression outstanding contribution. We know that the compression encoding = model, as a compression method, we must take full account of two model and coding module effectiveness; But at the same time, model and coding module of two mutual independence.

Description: This file contains a new and improved version of the Huffman coder, (June 29. 2001). The name is Huff06.m. There are also some additional files which are helpful when using Matlab for data compression: quantizer, different variants of run-length-encoding and end-of-block coding in Mat2Vec, and a program which do JPEG-like entropy coding. A complete compression example is shown in TestMat2Vec.m. This file is all you need for Huffman coding in MatLab.-This file contains a new and improved version of on of the Huffman coder, (June 29. 2001). The name is Huff06.m.
