Huffcomp Toolbox for SciLab
===========================
This small toolbox shows the principles of huffman coding. It consists of 6
routines and the corresponding help files. The Aim of the toolbox is to
demonstrate the principles. By the way, the coding functions are quite fast, the
decoding function could be optimized.
Content of the toolbox
==========================
6 routines are contained. These routines are
● fasthist
● huffman
● huffcode
● huffdeco
● huffmandict
● histcalc
Changelog
=========================
1.1 * speedup of huffdeco
* improvement of huffman
* some demos
