freq
周波数応答
呼び出し手順
[x]=freq(A,B,C [,D],f) [x]=freq(NUM,DEN,f)
パラメータ
- A, B, C, D
適当な次元
nxn, nxp, mxn, mxp
の実数行列 .- NUM,DEN
次元
mxp
の多項式行列- x
実数または複素数の行列
説明
x=freq(A,B,C [,D],f)
は次の関係を満たす実数または複素数の
mxp*t
行列を返します.:
x(:,k*p:(k+1)*p)= C*inv(f(k)*eye()-A)*B + D
.
ここで, f
が虚軸上または単位円上に
値を有する場合,
x
は連続系または離散系における
(A,B,C,D)
の周波数応答となります.
x=freq(NUM,DEN,f)
は,
x
の k*(p-1)+1
列から
k*p
列が行列NUM(f(k))./DEN(f(k))
を
含むような
実数または複素数の
行列x
を返します.
