polar

polar — polar form

Calling sequence

[Ro,Theta]=polar(A)

`A`	: real or complex square matrix
`Ro,`	: real matrix
`Theta,`	: real or complex matrix

[Ro,Theta]=polar(A) returns the polar form of A i.e. A=Ro*expm(%i*Theta)Ro symmetric >=0 and Theta hermitian >=0.



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