polar

極座標形式

呼び出し手順

[Ro,Theta]=polar(A)

パラメータ

A

実数または複素数の正方行列

Ro,

実数行列

Theta,

実数または複素数の行列

説明

[Ro,Theta]=polar(A)Aの極座標形式,すなわち, A=Ro*expm(%i*Theta), 対称行列 Ro >=0 およびエルミート行列 Theta >=0 を返します.

A=rand(5,5);
[Ro,Theta]=polar(A);
norm(A-Ro*expm(%i*Theta),1)

参照

  • expm — 正方行列の指数関数
  • svd — 特異値分解
