Detailed Description

Extracts the discrete-time state matrix implied by a real-valued EMT MNA model.

The extractor assembles the MNA-coupled state-space model

x[k+1] = AdLocal x[k] + BdMna xMNA[k+1] Y xMNA[k+1] = CdMna x[k]

where x is the extraction-state vector and xMNA is the full MNA unknown vector. Eliminating xMNA gives

Ad = AdLocal + BdMna * solve(Y, CdMna)
