Detailed Description

Port of matlab/src/api/sn/sn_rt_stations.m.

sn.rt is over STATEFUL nodes, and a Router or a Cache is stateful without being a station. Callers that need a station-to-station routing matrix must therefore eliminate the non-station stateful rows, not index around them: the reference forms the stochastic complement

rtst = P(A,A) + P(A,B) (I - P(B,B))^-1 P(B,A),

with A the (station, class) rows in STATION order and B the rest. That is exactly dtmc_stochcomp(rt, A), which is what this port calls; the explicit block form is only how the reference spells it.

Vst is cellsum(sn.visits) restricted to the same station rows, in the same order, so the two outputs are index-compatible.

ARITHMETIC: field. dtmc_stochcomp is a linear solve.
