**Abstract:**

The structure at infinity of a matrix pencil can be obtained by rank
determination of Toeplitz matrices. We show that the generic rank of these matrices equals the structural rank.
Thus the Toeplitz matrix approach is also suited for investigations of structure
matrix pencils. Computational results underline the efficiency of this approach.
