full rank factorization of A^k
[Bk,Ck]=fullrfk(A,k)
real or complex matrix
integer
real or complex matrices
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
.
