Estimating the states: the Viterbi algorithm.

The Viterbi algorithm [65] estimates the most likely state sequence. The command:

	states=viterbi(parm,x);

Outputs the most likely state sequence corresponding to data x. As a test, try the following commands:

     [x2,states]=hmm_synth_mex(parm,100);
     x2=x2';
     est_states=viterbi(parm,x2);

Compare the estimated states with the actual.
