pol2des

conversion matrice de polynômes vers forme descripteur

Séquence d'appel

[N,B,C]=pol2des(Ds)

Paramètres

Ds

matrice de polynômes

N, B, C

3 matrices réelles

Description

Etant donnée la matrice de polynômes Ds=D_0 +D_1 s +D_2 s^2 +... +D_k s^k, pol2des renvoie 3 matrices N, B, C, avec N nilpotente telles que :

Ds = C (s*N-eye())^-1 B

Exemples

s=poly(0,'s');
G=[1,s;1+s^2,3*s^3];[N,B,C]=pol2des(G);
G1=clean(C*inv(s*N-eye())*B),G2=numer(G1)
