MATLAB CODE FOR RANGE CODING Marc Servais (m.servais@surrey.ac.uk) 02 February 2004 ------------------------------------------------------------------------ This code is based on the Range Coding algorithm described at: http://www.arturocampos.com/ac_range.html Please refer to this site for more information. For an example of how to use this code, try running the files: "RangeCodingDemo.m" (Fixed Probability Model known to both encoder and decoder.) and "RangeCodingDemo2.m" (Adaptive Probability Model for encoding and decoding.) ------------------------------------------------------------------------ This code has been tested on Matlab 6.5 (R13). This package does not come with models for symbol encoding. You must create your own histograms for symbol probabilities. ------------------------------------------------------------------------ DISCLAIMER: BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
