Name
invr — inversion of (rational) matrix
Calling Sequence
F = invr(H)
Parameters
- 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)
