sylv

シルベスタ方程式.

呼び出し手順

sylv(A,B,C,flag)

パラメータ

A,B,C

適当な次元の実数行列.

flag

文字列 ('c' または 'd')

説明

X = sylv(A,B,C,'c') は "連続時間" シルベスタ方程式の解Xを計算する,

A*X+X*B=C

X=sylv(A,B,C,'d') は "離散時間" シルベスタ方程式の解Xを計算する,

A*X*B-X=C

A=rand(4,4);C=rand(4,3);B=rand(3,3);
X = sylv(A,B,C,'c');
norm(A*X+X*B-C)
X=sylv(A,B,C,'d') 
norm(A*X*B-X-C)
