Structure decomposition of normal 2D transfer matrices.
| The notion of the normal transfer matrix and the notion of the structure decomposition of normal transfer matrix for 2D general
model are introduced. Necessary and suﬃcient conditions for the existence of the structure decomposition of normal transfer matrix are
established. A procedure for computation of the structure decomposition is proposed and illustrated by the numerical example. It is shown that
the impulse response matrix of the normal model is independent of the polynomial part of its structure decomposition.
