fullrfk(1)

NAME
fullrfk - full rank factorization of A^k

CALLING SEQUENCE
[Bk,Ck]=fullrfk(A,k)

PARAMETERS

A   : real or complex matrix

k   : integer

Bk,Ck
    : real or complex matrices

DESCRIPTION
This function computes the full rank factorization of A^k i.e. Bk*Ck=A^k where Bk is full column rank and Ck full row rank. One has range(Bk)=range(A^k) and ker(Ck)=ker(A^k).

For k=1, fullrfk is equivalent to fullrf.
