Gegeben sei eine formale Potenzreihe \(S(x)=\sum^{\infty}_{i=0}s_ ix^ i\) mit \(n\times n\)-Matrizen \(s_ i\) als Koeffizienten. Zur Berechnung von (Matrix-) Padé-Approximationen von S(x) wird ein rekursiver Algorithmus explizit angegeben, der auch dann arbeitet, wenn die Potenzreihe nicht normal ist.
