inverse of polynomial matrix

Calling Sequence




square polynomial matrix


coffg computes Fs^-1 where Fs is a polynomial matrix by co-factors method.

Fs inverse = Ns/d

d = common denominator; Ns = numerator (a polynomial matrix)

(For large matrices,be patient...results are generally reliable)


a=[ s, s^2+1; s  s^2-1];
