# arma2p

ar形式から多項式行列を展開

### 呼び出し手順

[A,B,D]=arma2p(ar)

### パラメータ

A,B,D

ar

arma保持王のScilab 'ar' tlist (armac参照).

### 説明

この関数は,armax記述から多項式行列(A,B,D)を 展開します.

### 例

a=[1,-2.851,2.717,-0.865].*.eye(2,2)
b=[0,1,1,1].*.[1;1];
d=[1,0.7,0.2].*.eye(2,2);
sig=eye(2,2);
ar=armac(a,b,d,2,1,sig)
// extract polynomial matrices from ar representation
[A,B,D]=arma2p(ar);
