A stochastic matrix describes a Markov chain Xt over a finite state space S with cardinality α. If the probability of moving from i to j in one time step is Pr(j i) = Pi,j, the stochastic matrix P is given by using Pi,j as the i-th row and j-th column element, e.g., Since the total of transition probability from a state i to all other states must be 1, thus this matrix is a right stochastic matrix.
