arcoDemo

Interactive visualization of Elias and arithmetic coding.

arcoDemo provides an interactive visualization of two algorithms for compression of data streams: arithmetic coding and its predecessor, Elias coding.

The demonstration allows a user to specify the source alphabet, the underlying probability distribution, and the precision of the floating point arithmetic, in which the algorithms are to be implemented.

Examples:
p = [0.4 0.3 0.2 0.05 0.05]; arcoDemo(p,53,'arithmetic',[],1);
arcoDemo(p,24,'elias');
arcoDemo(p,24,'elias',{'l','e','o','h','!'});
