Sorry let me clarify: toarray() is a property of the sparse arrays which are produced by some of the transition matrix builders (transpose/row normalize mainly). It's useful when you have a very large MSM. Others produce a ndarray which don't have a toarray() method (the toarray method converts a sparse array to an ndarray).
