Multi-order State-transition Matrix

Construct a multi-order state-transition matrix.

Construct a multi-order state-transition matrix given a Markov chain (in integer).

Example:
markovChain = [1 6 1 6 4 4 4 3 1 2 2 3 4 5 4 5 2 6 2 6 2];
norder = 2;
[ transitionMatrix columnStates ] = getTransitionMatrix(markovChain,norder);
