LZW Compression (MATLAB Source Code)

This document introduces the LZW compression algorithm and provides downloadable MATLAB source code. LZW compression is a widely-used algorithm that effectively reduces data size while maintaining data integrity. One significant advantage of LZW compression is its ability to conserve storage space and reduce transmission time. The MATLAB implementation demonstrates key aspects including dictionary management using hash tables, pattern recognition through string matching, and efficient encoding/decoding procedures. The source code contains practical examples that illustrate how to implement the LZW algorithm, featuring functions for initializing the code dictionary, processing input streams, and handling variable-length code output. These examples help users understand the core compression mechanism where frequently occurring sequences are replaced with shorter codes, and the decompression process that reconstructs the original data using the same dictionary building methodology.
