I am looking for octave- or matlab-code, that allows me to find the
roots of the polynomial of x that results from det(H)=0, where the Hij
are polynomials in x theirself.
E.g.: find the roots x for
3x-4 2x+9
det ( ) = 0
-x+22 4x-11
I can program such a procedure myself (with successive convolution),
but this problem seems standard enough to me, that there could be a
procedure out there in octave-land.
Any hints?
