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.
老外的超高效率壓縮,High efficient Data Compression Library for use with Delphi.
Support Rank, ZIP, BZIP and PPM compression algorithms.
Compression ratio more than 1.5-2 times better than ZIP/RAR archiver.
Compression speed up to 8 Mb/sec (on PIII-600).
zlib is designed to be a free, general-purpose, legally unencumbered -- that is, not covered by any patents -- lossless data-compression library for use on virtually any computer hardware and operating system. The zlib data format is itself portable across
this book mainly includes these contents :linked list, stacks and queuse, recursions, binary tree, multi tree, graphs, sorting, hashing, data compression.
