nlev(1)

NAME
nlev - Leverrier's algorithm

CALLING SEQUENCE
[num,den]=nlev(A,z [,rmax])

PARAMETERS

A   : real square matrix

z   : character string

rmax
    : optional parameter (see bdiag)

DESCRIPTION
computes:
(z*eye-A)^(-1)
by block diagonalization of A followed by Leverrier's algorithm on each block.

Remark
This algorithm is better than leverrier but still not perfect!
