# minreal

### 呼出し手順

`slb=minreal(sl [,tol])`

### パラメータ

sl,slb

`syslin` リスト

tol

### 説明

`[ae,be,ce]=minreal(a,b,c,domain [,tol])` は線形システム`sl` (`syslin` リスト) の平衡実現を返します.

`sl` は安定であると仮定されます.

`tol` 閾値は `equil1`で使用されます.

### 例

```A=[-eye(2,2),rand(2,2);zeros(2,2),-2*eye(2,2)];
B=[rand(2,2);zeros(2,2)];C=rand(2,4);
sl=syslin('c',A,B,C);
slb=minreal(sl);
ss2tf(sl)
ss2tf(slb)
ctr_gram(sl)
clean(ctr_gram(slb))
clean(obs_gram(slb))```
