Computing the inverse of polynomial matrices

Dear all,
Considering a polynomial matrix of the form
A(z)=z^n*A_n + z^{n-1}*A_{n-1}+...+z*A_1+A_0 where the A_i are real _square_ matrices,
Are there Matlab functions designed to compute the inverse of such a polynomial matrix ?
Any advice or comment is welcome,
Thank you,
Raphaël

I have noticed that you cannot easily calculate the inverse (symbolic or not). I just read a paper describing an algorithm on how to do the inverse and get an expression of the inverse as based on A_i.
In scilab there is function doing this (calculating coefficients) and if you have POLYX software (which is not free), you will be able to do it as well in MATLAB. I haven't come up with a solution yet. But I think I have to implement the algorithm myself.
Cheers Keivan
