Detailed Description

One point of a transient trajectory: the metrics at time t.

getTranAvg in the reference returns QNt/UNt/TNt as (station x class) cell arrays of time series; this carries the same information sampled at a grid, which is what a caller plots or integrates.

◆ QCov

Matrix<double> line::fluid::FluidTranPoint::QCov

The same second moment as a FULL (M*K)-by-(M*K) covariance, indexed ir = r*M + i, empty wherever QVar is.

QVar is its diagonal reshaped; the off-diagonal entries carry the cross-station and cross-class terms a per-pair variance drops, which is what a coupling carrying a distribution across a handoff needs – SolverEnv's meancov is the case it exists for.

◆ QVar

Matrix<double> line::fluid::FluidTranPoint::QVar

Per-(station,class) queue-length VARIANCE at this instant, empty where the method carries no second moment along the trajectory.

Only the dae route fills it, and only below FluidDaeOptions::maxcov: the moment closures evaluate their whole transient at the single stationary variance, so a per-point variance would be the same number repeated.
