any matlab function/source code for huffman encoding

Dear all,

I am looking for matlab source code for huffman encoding such as those used
in JPEG...

I hate C code since I guess I need 10x more time to modify it to suit my
need; but with matlab code it is more understandable and modifiable...

My need is to see a 16x16 picture block, if using Huffman encoding... needs
how many bits....(need accurate bit counting, and do not want get the
overhead of jpeg header file...)

Please help me!

Thanks a lot,

-Walala
