[inline, protected, virtual]

Discrete Time Markov Chain: In theory, these equations are solved for vectorN: 1) vectorN = vectorN * matrixT <=> 0 = vectorN * (matrixT - I) 2) vectorN * vector1 = 1 This is performed by doing a LU decomposition.

Reimplemented from wns::markovchain::MarkovBase< T >.

Reimplemented in wns::markovchain::MarkovDiscreteTimeTraffic.
