arithenco

This function encodes the given sequence using aritmetic coding

Syntax

CODE = ARITHENCO(SEQ, COUNT)

Description

CODE = ARITHENCO(SEQ, COUNT) encodes the given sequence (SEQ) using arithmetic coding. COUNT is vector whihc gives information about the source statistics (i.e. frequency of each symbol in the source alphabet) CODE is the binary arithmetic code Source Alphabet is assumed to be {1,2,....N} where N is a positive integer Therefore, sequence should be finite and positive Length of the COUNT should match the length of the source alphabet

Examples

counts = [40 1 9];
len = 4;
seq = [1 3 2 1]
code = arithenco(seq,counts);
disp(code)
