Petry's efficient and optimal variable to fixed-length source code for discrete memoryless sources was described by Schalkwijk. By extending this coding technique we are able to give an algorithm for Markov sources that is easy to implement. We can bound the loss of efficiency as a function of the code complexity and the mismatch between the source and the code. Rates arbitrarily close to the source entropy are shown to be achievable. In this sense the codes introduced are optimal.
