Scilab Function

glever - inverse of matrix pencil

Calling Sequence

[Bfs,Bis,chis]=glever(E,A [,s])

Parameters

Description

Computation of

(s*E-A)^-1

by generalized Leverrier's algorithm for a matrix pencil.

(s*E-A)^-1 = (Bfs/chis) - Bis.
   

chis = characteristic polynomial (up to a multiplicative constant).

Bfs = numerator polynomial matrix.

Bis = polynomial matrix ( - expansion of (s*E-A)^-1 at infinity).

Note the - sign before Bis.
