To solve ![[Graphics:../Images/ZTransformDEMod_gr_39.gif]](../Images/ZTransformDEMod_gr_39.gif){kind=small}
with ![[Graphics:../Images/ZTransformDEMod_gr_40.gif]](../Images/ZTransformDEMod_gr_40.gif){kind=small}
, we
will use our Mathematica subroutine ![[Graphics:../Images/ZTransformDEMod_gr_41.gif]](../Images/ZTransformDEMod_gr_41.gif){kind=small}
for
finding the solution to ![[Graphics:../Images/ZTransformDEMod_gr_42.gif]](../Images/ZTransformDEMod_gr_42.gif){kind=small}
. It
will construct the characteristic polynomial and its
roots. The format of the subroutine call
is ![[Graphics:../Images/ZTransformDEMod_gr_43.gif]](../Images/ZTransformDEMod_gr_43.gif){kind=small}
