equil1
行列の平衡 (非負定) の組
呼び出し手順
[T [,siz]]=equil1(P,Q [,tol])
パラメータ
- P, Q
非負定の対称行列
- T
正則行列
- siz
3要素の整数ベクトル
- tol
閾値
説明
equil1
は次のような t
を計算します:
P1=T*P*T'
および Q1=inv(T)'*Q*inv(T)
は以下のようになります:
P1 = diag(S1,S2,0,0)
および Q1 = diag(S1,0,S3,0)
ただし,
S1,S2,S3
は各次元がsiz=[n1,n2,n3]
の正定対角行列です.
tol
はSVDのランク定義の閾値です.
