Displacement structures for confluent polynomial Vandermonde matrices

In this Note, we show that the useful displacement structures constructed for polynomial Vandermonde matrices (see [9]) in particular) can be naturally extended to confluent polynomial Vandermonde matrices. This result was made possible by virtue of the fact (recently established by the author in [11]) that confluent Vandermonde matrices belong favorably to the class of structured matrices.
