invr

inversion of (rational) matrix

Syntax

F = invr(H)

Arguments

H

polynomial or rational matrix

F

polynomial or rational matrix

Description

If H is a polynomial or rational function matrix, invr computes H^(-1) using Leverrier's algorithm (see function code)

Examples

s=poly(0,'s')
H=[s,s*s+2;1-s,1+s]; invr(H)
[Num,den]=coffg(H);Num/den
H=[1/s,(s+1);1/(s+2),(s+3)/s];invr(H)
