nlev
Leverrier's algorithm
Calling Sequence
[num,den]=nlev(A,z [,rmax])
Arguments
- A
real square matrix
- z
character string
- rmax
optional parameter (see
bdiag
)
Description
[num,den]=nlev(A,z [,rmax])
computes
(z*eye()-A)^(-1)
by block diagonalization of A followed by Leverrier's algorithm on each block.
This algorithm is better than the usual leverrier algorithm but still not perfect!
