Markovian transition matrices are necessarily square.That is, there are exactly the same number of rows as there are columns.

Question

Quizplus · Accepted Answer

Markovian transition matrices represent the probabilities of transitioning from one state to another, and since each state can only transition to another state (including itself), there are as many possible transitions as there are states. Therefore, the matrix must be square with the same number of rows as columns.
