polar

極座標形式

呼び出し手順

[Ro, Theta] = polar(A)

引数

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) は, Aの極座標形式を返します. 対称行列 Ro >=0 および エルミート行列 Theta >=0 の時, A=Ro*expm(%i*Theta)となります.

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

B = complex(5,7)
[M, P] = polar(B)
M * exp(%i * P)
