Codes".
Huffman coding uses a specific method for choosing the representation for each symbol, resulting in a prefix code (sometimes called "prefix-free codes") (that is, the bit string representing some particular symbol is never a prefix of the bit string representing any other symbol) that expresses the most common characters using shorter strings of bits than are used for less common source symbols. Huffman was able to design the most efficient compression method of this type: no other mapping of individual source symbols to unique strings of bits will produce a smaller average output size when the actual symbol frequencies agree with those used to create the code. A method was later found to do this in linear time if input probabilities (also known as weights) are sorted.

huff
呃，就是用赫夫曼算法写的压缩解压程序。非常粗糙，只能压缩英文文章。因为里面的字符概率是基于自然语言的，源代码之类的没法压缩。而且会抛弃最后几个字母，嘿嘿。为了交作业，没有好好写。改一下下应该能挺好的。压缩比能到60 吧(Uh, is to use Huffman compression decompression algorithm written procedures. Very rough, only compress English articles. Because there is the probability of characters based on natural language, the source code and the like can not compressed. And will abandon the last few letters, hehe. For homework, not properly written. The following should be able to change it quite good. Compression ratio to 60 of it can be)

celp
CELP (CELl Processing) is a functional programming package for Matlab.
It is often better to use FP instead of loops:
- it s more compact
- it s more clear.
