Arithmetic coding, the way to find decimal representation of codeword

seq = [3 3 1 3 3 3 3 3 2 3];
counts = [10 20 70];
code = arithenco(seq,counts)

By implementing this code, I can get arithmetic codeword in matrix

[1 0 0 0 1 1 0 0 0 1 0 1 1 0 1 1 0 0]

it means that it is '0.100011000101101100' in binary.

I want to know average codelength to get code efficiency, so I must know convert the codeword into decimal and get length of it.

I can calculate it easily beacuse above example is not large, however I want to know how to calculate the length in large cases(my codeword in binary length is 5897909)

Hi,

You can get the length of the code word using 'size' function

lengthOfCodeWord = size(code,2);
